Factory stored uranium for nuclear weapons

Twenty miles northwest of Cincinnati is the small farming town of Fenald, Ohio. For many years, the town’s main employer was “The Feed Materials Production Center,” also known as N.L.O. Unknown to the public, NLO was actually owned by the Department of Energy. From 1953 to 1989, it was one of the few plants in the United States that secretly processed high-grade uranium for nuclear weapons. Former N.L.O employee Harry Easterling believed the plant was safe:

“When I was hired, they said that it was a low level radiation plant. They told me there was nothing back there that would bother you and to just go on about your business. Don’t tell anybody what you were doing and everything would be fine.”

But conditions at the plant weren’t fine. In the fall of 1984, N.L.O. was rocked by scandal when a factory accident released massive amounts of radioactive smoke into the atmosphere. An investigation later revealed that, over the years, N.L.O. had released more than 200 tons of radioactive dust particles into the air and local water sources. Reporter D.C. Cole investigated the story:

“We had an environmental disaster. I think if you did a survey around the Fernald community now, you would find very few people who trust the government.”

Tons of radioactive materials leaked out

In June of 1984, just a few months before the N.L.O. disaster, one of the plant’s employees, Dave Bocks, died a gruesome death inside the factory. His family was convinced he was murdered, possibly because he was going to blow the whistle on the quantity of radioactivity the plant was releasing.

Dave was hired at N.L.O. as a pipe fitter in 1981, and quickly earned the trust and respect of his co-workers. Dave was divorced, but remained close to his ex-wife and three children. Casey Drake is Dave Bocks’ daughter:

“He was great. He would do anything for us. Kind as can be, loved his children, did his job.”

Dave worked the graveyard shift. On Sunday night at 11:00 PM, he met his rideshare partner and co-worker, Harry Easterling, in the parking lot at a local restaurant as usual:

Bocks’ keys didn’t melt, raising suspicions

“Dave got into my truck, we left, had a little conversation on the way to work. He had talked about vacation with his kids and bought a new lunch box for work. Everything seemed to be normal.”

Dave’s job was to inspect and maintain equipment throughout the factory. This included making sure that the safety pumps and dust collectors used in the uranium processing were working properly. Harry realized Dave was aware of what the factory was doing:

“Dave was a fairly quiet guy, but if you worked on a job, and it was high radiation level, Dave would tell you, ‘You know, that particular dust collector is fairly radioactive, so watch yourself,’ or, ‘That pump has a certain kind of acid in it so be careful when you work on it.’”

Only the maintenance crew and security personnel worked the graveyard shift. The production lines were shut down. At midnight, Dave reported to the maintenance room for his assignment. Harry recalls that the night began just like any other:

“Dave opened up his tool box and left his keys and lock on top. He went to one area and I worked on a job at another plant.”

A worker saw Dave and a supervisor in a parked pickup truck. He said Dave and the supervisor seemed to be having a “serious discussion”, but he could not tell what they were talking about. He noted that the windows of the truck were rolled up, even though the weather was hot and humid.

An hour later, the same witness ran into Dave on the factory grounds. He noticed that Dave was walking towards Plant 4, not Plant 8 where he’d been assigned. It was the last time Dave Bocks was seen alive. Later that morning, Harry Easterling became suspicious because he hadn’t seen Dave in hours:

“At approximately 7:00 that morning, we had a safety meeting in the conference room in Plant 4. We showed up for the meeting, but Dave wasn’t there. I walked back over to the maintenance building, put my tools away, and noticed that Dave’s toolbox was still open. I thought he was probably working overtime so I went in, made a few phone calls, but still couldn’t locate him. I went back out and told the security guard at the desk that Dave hadn’t come out, I was going home, and I would meet him the next night at the restaurant.”

At around 7:30 that morning, a furnace operator in Plant 6 told his supervisor that the casings in his oven were covered with a strange, sticky residue. The worker also noticed a strange odor. The supervisor apparently found nothing wrong and told the furnace operator to go back to work.

On the way to his next shift, Harry went to the restaurant to meet Dave as usual. It was Dave’s turn to drive, and his car was already there:

“There wasn’t anything out of the ordinary because he would go pull his car in and go get something to eat or get something to take for lunch and then come back to the car. I leaned up against Dave’s car, and I noticed that the fender was still cold. So I reached over, touched the hood and it was still cold.”

Harry was worried. When he got to work, he reported Dave missing and had a security guard pry open his locker. Inside the plant, an investigation had begun. Plant records show that at 5:15 on the morning Dave disappeared, the temperature in the furnace in Plant 6 had briefly dropped 28 degrees. This sudden change suggested that something “foreign” had been dumped into it. A worker also found what appeared to be piece of bone on the lip of the furnace. The Sheriff’s Department was called in and the furnace was shut down.

It took three days for the molten liquid inside to cool. When employees searched through the waste material, they found a set of keys. Former Hamilton County Police Chief, Deputy Sheriff Victor Carelli, investigated the case:

“The keys found belonged to the victim’s car. They also belonged to three padlocks of his, and one key we believed went into his residence but we couldn’t prove that because it was bent and not very good shape.”

If the keys pulled from the furnace were Dave’s, they would presumably have fallen in along with the “foreign body” at 5:15 AM. But if Dave’s keys were seen more than two hours later in his toolbox, how did they get into the furnace?

Investigators concluded that Dave was probably dead. Harry was stunned. He was also confused about Dave’s keys:

“When I left the plant to go over to the maintenance shop, his keys were in the box. When I left there, to go home, they were still in the box. I went home. When I came back that night, his keys were still in the top of his toolbox. The supervisor closed his box, put the lock on his toolbox and took his keys out of the lock. And from there on I do not know what happened to the keys.”

Besides the keys, investigators found a steel toe from a boot, part of an eyeglass frame, fragments of Dave’s walkie-talkie, and a stainless steel wire that was looped together in three oddly connecting circles. Also recovered were several pieces of human bone.
Investigators were unable to determine how Dave ended up in the furnace. They suggested that he might have committed suicide. Dave had a history of psychological problems, and around the time of his divorce, he had apparently tried to kill himself. Dave Bocks’ daughter, Casey Drake believes otherwise:

“I know my father did not commit suicide. He had purchased groceries for the week. He was planning a vacation with my younger brother and me for the following summer to Florida, and he had paid all of his bills for the month. There was no reason for him to commit suicide.”

Former N.L.O. employee, David Day agrees:

“He was probably lowered into the furnace and murdered. I can’t think of any other way that it could have happened. I don’t believe that it could have been suicide or that it could have been an accident.”

Investigative reporter, D. C. Cole believes he knows why Dave Bocks may have been murdered:

“I think he knew something. It’s possible that he was a whistle blower or was going to be a whistle blower. Plant 8 had released four times more radioactive contaminants into the environment than any other plant at the plant site. I believe that they could have either shot him, or they could have hit him with something and knocked him unconscious. They took the body back to Plant 6, where the furnace is. I would hate to think that he was conscious. I can’t imagine a more horrible death than that.”

According to former Chief of Police Victor Carrelli, the evidence for murder was never there:

“No one ever gave us any indication or reason to believe that foul play may have occurred.”

Harry Easterling hopes someone might come forward and tell what they know:

“There are probably people out there that know what happened, and there may not be. Either way, if they did, I doubt anybody would tell for fear of their life.”

In 1989, five years after Dave Bocks’ death, the N.L.O. was shut down. Sadly, years later, Dave’s family is still unable to lay him to rest. Dave’s remains are just a few bone fragments and are too toxic to be buried in the ground. They have been sealed in a drum, and shipped off to a Nevada test site to be stored with other radioactive materials.

How Dave died and why remains a mystery.

    This was an insurance case. They didn’t want to pay out for an accident. Because that would have been thousands of dollars. So they bring up the homicide possibility. Dave was a good person. The plant wouldn’t have stayed operating without his good services. In fact it completely shutdown shortly after his death. But they had him working in an area he was unfamiliar with. And his equipment was not sufficient. The circles found are consistent with what they used for harnesses back then.


  2. Hector

    Did they ever talk to the supervisor? He seems to be a perfect suspect in this case.

      That reenactment with the crane didn’t happen. Just to fit that in the room would have been a challenge. And you can’t just fist fight someone on top of the boiler.


  3. Scott Shrout

    This is another one of the more bizarre stories featured on the show (Dale Kerstetter is another that comes to mind and interestingly it seems some in the discussions mix up the facts about the cases).
    The Dave Bocks case sadly will probably never be solved as there is no physical evidence that remains aside from the bone fragments that were put into storage. I actually visited the Fernald site a number of years after it closed (around 2006 I believe) and even then there was little to suggest a plant every existed there.
    It’s a very tragic and strange case indeed; I suspect Dave was indeed murdered, but absent a deathbed confession it’s unlikely we will ever know the truth.


  4. Tony Bocks

    I have given up on believing that an end would ever come in my dad’s case. I guess it was already over in 1984. I love my dad and have prayed that justice will be served. But God hold a special place in hell for the people that a respo sible for destroying my dad and really make life terrible for my sister brother and I. Please. If someone knows anything I beg you to go to the authorities.

      I’m soooo sorry. I worked there for a year and a few months, one year in the print shop which was and ancient building that had zero exhaust only old crank open windows, no masks, and I’m inhaling all of the binding glue for eight hours…That’s just in the print shop, so I finally realized what was making me deathly I’ll So I complained, then they put me in the mail room delivering mail to different buildings for a month. While delivering mail I was told the one side of a chain link fence was the hot side and the other side was the cold side??? What the??? Ok, so then became a secretary for a couple months, but the glue had done its damage to my lungs and they still do not acknowledge that I even worked there, their excuse is they can’t find my paperwork and I even had a great job letter from my supervisor…This is our Government we are talking about…it’s a sad country… I hope you happiness and healing, GOD BLESS YOU


  5. Kevin Gibbs

    Mr. Bocks, you need to contact an attorney to force DNA testing on the wire wrapped in 3 interlocking circles, seems like it could be plausible that the 2 circles side by side were used as a restraint & the left over ring was probably used as a handle to control the movements of your father prior to his death. Also, the FBI has a department or division that handles corruption. NLO was owned by the DOE, have your attorney go after them & the direct supervisor of your father, seems plausible that anyone who had reason to fear your father’s (possible) whistleblowing has reason to be considered a suspect. If the DNA on the wire comes back to someone with a record, you would at least have someone with knowledge of events of the day or night your father died.

    Always remember, your father is with the Lord. You have my condolences. May he rest in peace. God bless.


  6. Kaye

    It’s not rocket science… he was murdered and hopefully those involved are suffering or have suffered for what they’ve done to David Bock and his family.

    It’s very sad and it’s disturbing that they may have gotten away with murder.


  7. Don

    Anyone who had seen the salt furnace while under heat would immediately know suicide would have been impossible. The large rectangular furnace’s lid covered the complete top and was opened on the ends with a few steps going in. The lid required the overhead crane to lift so was a major event to remove and put back (requiring a crane operator). It was not possible to crawl into the furnace ends as the heat was so intense it would drive you back. I worked as a production engineer in Plant 6 from 1986-1989. Though I was not there in 1984 I was told by a fellow, well respected, engineer that his death may have been an accident, maybe getting hit by a fork truck and his body disposed of in the furnace (panic reaction by the driver). The other theory was maybe he witnessed a drug deal going down, was murdered, and the body disposed of in the furnace. Bottom line he was dead before his body was put into the furnace.

    I used to live across the street from Fernald starting in 1990. Even then, there were areas where the liquid chemicals leaked into the water system. We believe that my mother developed cancer 7 times from our 6 years there. She has survived each bout with cancer, but I am now an environmental researcher. There is credible evidence that they have not stopped the pollution even though the plant closed in 1989. Something is still being kept quiet…


  9. Anon

    The lack of a suicide note is automatically suspicious.


  10. Bill Blaski

    Just listened to the accused podcast about David. I can’t help but to side with the homicide theory. Either the supervisor or the guy Dave told on who was sleeping in the plant. Per the podcast the sheriff’s dept is opening this case again. There is no way Dave Cannon balled or dove into that furnace! I also had no idea that DC Cole was such a loon. So sad all these people are dying that worked at Fernald.


  11. Eddie

    The keys did not melt because they were thrown in there at a later time. They were in his toolbox for a while before being taken by the supervisor. With the information we’ve been given about the character of that plant and the powers that be who run it, there’s a good chance that same supervisor threw the keys in the furnace. I have never studied law and I don’t know a whole lot about all the ends and outs of it, so I don’t know if polygraph tests can be forced on someone or not. But there are some individuals who definitely need to take them, that’s for sure!


  12. Bill Blaski

    Just downloaded Pluto TV app. It has its own unsolved mysteries channel 334. Just got done watching this story about Dave Bocks. Was it sucide or murder? This needs looked at!


  13. Jason

    I was gonna say, don’t mess with the DOE. They have snipers and high security. The camera shot of this poor gentleman being lured into the vat stuck with me for yrs.

    This is obviously murder and covered up. I belive he was gonna go public with the venting of toxic gases and he was probably warned and was eventually killed so he wouldn’t expose the corruption that we, as Americans, are so sick of. God bless you Dave and your family


  14. Oliver

    Wow…all that toxic waste released into the atmosphere is a tragedy in it’s own…I sure hope they find the people responsible for Dave’s demise!


  15. Mark

    Very high chance he was murdered then tied up with the wire found and attached to a machine where he was hoisted into the furnace. How he died is unknown but since no bullets were found it probably was strangulation. Motive could be he found out something and needed to be kept quiet. if the supervisors and managers had been given a lie detector test they could of used that to develop a suspect and go from there to get proof needed to convict. You have to put enough effort to solve a case like this like when Osama bin laden was eliminated it took what ten years but we never stopped until the job was finished.


  16. Tony Bocks

    I am Tony Bocks. I am the oldest son of David Bocks. I have dead the posts on this site, I want to thank all the kind posts on behalf of my dad. I want to thank you all for your prayers, we still need them. If ANYONE has ANY I formation about this PLEASE come forward. Our family has NEVER been the same since . And I will say unequivocally that my dad DID NOT commit suicide. There has been TOO MANY COINCIDENCES for that ro be true


  17. doug thompson

    No lie detector test given to that supervisor ??????????
    Plain as day (Supervisor and certain investigators) were involved and clearly
    got away with MURDER !!!!!!!


  18. Bill Blaski

    Again I nominate this case to be on the new unsolved mysteries. So baffling


  19. Raoul Kopecknie

    Ok, Nowhere do I find a decent fact filled version of this man’s death. Everyone assumes it was murder, but there are ZERO pictures of the furnace, the area around it, or the Flue. More importantly, IS THERE ANY possibility he could have fallen in? How did the furnace exhaust?

    As for the keys, has it occurred to anyone that he had two sets of keys? One for his home and auto, that could have been left on his toolbox, and a second set of keys to the plant? The article never addresses this, nor what happened to the set of keys with his tool box.

    As for getting ready to expose the plant, Karen Silkwood style, this was a DOE facility. The man had worked there for several years and was not the sort to make waves. Being a federal facility, the Federal government would have had many avenues of recourse other than a nefarious murder to keep him quite, for example non disclosure and National Security laws which would have left him in the slammer for life.

    Additionally, how much production was lost as the furnace had to be shut down for several days due to the remains being found. DOE sites also have really nasty acids that would dissolve a body, and contaminated drums that will NOT be touched for hundreds or thousands of years. And you think they would dispose of a body in a furnace?

    The man worked the night shift. No doubt he was comfortable, likely too comfortable with acting alone when problems presented themselves. This happened in 1984, when I don’t think lock out /tag out precautions were exactly in widespread use. . .

    Occam’s razor. . The simplest explanation is probably the truth. A major conspiracy it not.

    the supervisor did and God will burn u in the lake of fire for it

    Re-interview every single person in that plant the night he went missing.

    ..it was Murder, when a person commits suicide, it is done quick and with the least amount of pain possible. I hope to God they find the killer, they not only murdered him but emitted radiation to many innocent lives.


  23. Anonymous

    I believe he was murdered, quite brutally, for being a whistleblower. What an agonizingly gruesome death this poor man endured. RIP Dave.


  24. Tony T

    The Department of Energy has been falsifying cancer risk reports at the Fernald site since the mid ’90’s, with no end in sight. This is criminal…


  25. Leigh

    It seems to me that the keys being seen at a different site after the victim is suspected to have died, and then showing up in the furnace, would be all the evidence needed to call this a homicide. I’m no genius, but obviously someone other than the victim threw the keys into the furnace. This is a terrible story.


  26. Blue bird

    Ok… um I am totally Confused! How Come His Keys Did Not Melt? And I Think He Was Murdered! Or He Accidentally Slipped And Fell Or He Could Have Jumped In And Committed Suicide Or Was It A Conspiracy? Perhaps He Was Being Threatened By His Employers!


  27. oonai

    I think it’s pretty obvious that it was suicide.


  28. Junior

    I believe this man was murdered for attempting to blow the whistle to set things straight. Poor guy. My heart goes out to the family. R.I.P. Mr. Bocks.


  29. Kenneth McDonald

    Check up on anyone in the plant reading H. G. Wells – The Cone


  30. steve

    “stainless steel wire that was looped together in three oddly connecting circles”

    Sounds like something to tie hands and feet together. 2 circles for legs and 1 for hands


  31. Johnny

    I was a teenager when I watched this episode. Poor Mr. Bocks! It looked like a sprawling plant with many winding steps and levels. It definitely appeared to be murder. Not many people on the nightshift. Somebody with an accomplice probably killed Mr. Bocks. I feel sorry for his grown kids now.


  32. Alan

    Wouldn’t the keys dissolve in that heat, the looped wres are the most suspicious I believe.were they big enough to loop around his legs and hold weight.?


  33. Mike

    I believe the police did a very poor job at this investigation. I say this because of the “Keys Evidence”. His keys were seen in the toolbox after he known to be missing. Then a supervisor took them out and took the keys. The next place they were found was in the furnace where his body was… HELLO?! Who ever was involved with the murder threw those keys in there and gave themselves away! The police might want to throw some muscle into interviewing the supervisor that took the keys!

    The fact that they would even consider this a sucicide is suspicious on behalf of the police. It looks like they might be involved in the coverup to ignore obvious evidence like that.


    • Jason

      I’m pretty sure the Dept of Energy (Federal) owns the police (state). You don’t mess with the federal gov and get away with it.

    It was a short dude about 5 ft 2 in his fifty



    Few realize NLO had a sister plant in Albany NY, NL Industries. The plant had to be razed costing over 200 million due to from DU and U contamination, as well as a long list of carcinogens. Many are dead and still dying or sick; including myself – 21ft of Earth under the plant, rooftops, yards all removed. The Uranium was detected over 20 miles away and rained down over neighborhoods from incinerators for decades – all to make DU munitions; the very reason we leave our military equipment in the Gulf. It’s all radioactive. The only difference, although FERNALD settled, NO LAWYER HAS EVER COME TO OUR RESCUE. 2015


  37. Gen

    This is a story I never forgot about from the 1st time I saw it when this show was on air. And yes I believe it was murder. I feel terribly still for Mr Bocks& his family. The greedy & powerful always get away w evil deeds like this.


  38. paul

    first I want to offer my deepest sympathies to the Bock family. I worked for a nuclear contracter in Nevada my years ago. My employer I came to find were well connected organization. Later I learn the hard way how serious these people. In the NRC (nuclear regulatory commission) Many of then shareholdes are very rich and people and they want to keep it that way


  39. Ryan Britt

    So this episode on Unsolved Mysteries. What a very bizarre story. Seems like something u would see in a movie. R.I.P


  40. Brett

    I know I already posted on here once already but I would just like to add I feel so sorry for dave bocks and his two son’s and his daughter I hope one day you find out what really happened and I hope who ever did this to your dad pay’s for what they did


  41. Brett

    i to belive he was killed the fact is if you know something wrong is happing and you try to report it somebody who is doing the wrong is about to be found out they will shut you up I feel sorry for him but you cant trust very many people in life most of all you cant trust the government or the police


  42. Scott

    RIP David


  43. Scott

    An awful story. I pray for the family of David. RIP David Bocks
