Three investigators tried to solve the mystery of what happened to Karen Silkwood on that dark highway the night of November 13th, 1974. An accident investigator hired by the union believed so strongly that Karen’s car had been forced off the road that he saved the bumper as evidence, handing it down to his daughter on his deathbed. A private eye pieced together a theory that Silkwood was under surveillance. And a state trooper launched his own investigation inside law enforcement. They all hit dead ends. Or did they?

Chapter 1: What happened during the road trip to Albuquerque?
I am hoping that we actually find some of the keys we need to begin to put a close on this case. I mean, you and I have been chasing this thing for years. And it took a lot to dig out this information that's in New Mexico that we're hoping is what we think it is. And I'm just really anxious to get there and start looking.
We decided to drive all this way.
I mean, we could have flown, but I do hate flying.
Yeah, I was tempted to say, meet you there. But eight hours in a car? That's nothing when you think about the thousands of hours we put into investigating Karen Silkwood's story.
At the end of this road trip, there was a crucial piece of evidence we wanted to see. Evidence that had been passed down in a family from one generation to the next. Our journey to uncover that piece of evidence had finally brought us here.
Hi. Nice to see you.
Here we met another Karen in this story. Karen Pipkin Guerrero greeted us at the front door.
Welcome to Albuquerque.
It's really good to be here. Come on in, guys. Thank you.

Chapter 2: What crucial piece of evidence was found in Albuquerque?
I feel like it should have gloves on to touch it. What we were looking for was perched on top of a refrigerator underneath some fishing rods next to a jug of windshield wiper fluid. Can I take it down?
Sure. Oh, yes. Please take it down.
Okay. And just like that, we were holding the bumper from Karen Silkwood's 1973 Honda, the car she was driving the night she died on that Oklahoma highway 50 years ago. I had this vision that it was going to be in some hermetically sealed glass case. You know, here was this key artifact of the Silkwood story.
And there it was, more than 500 miles from the crash site, gathering dust in a garage in Albuquerque, New Mexico. Wow. My God.
Holy mackerel, there's black stuff in it still.
Yeah.
Is that good? Yes.
Yeah, it's good. That's exactly what they were talking about.
The reason Karen Pipkin Guerrero has this bumper is because her dad was an accident investigator. And Karen Silkwood's union, the Oil, Chemical, and Atomic Workers Union, hired him to look into what caused the fatal crash.

Chapter 3: What did A.O. Pipkin conclude about Karen Silkwood's accident?
At that time, I found a white female behind the steering wheel of a small foreign car, and she appeared to be dead at that time.
All in all, he stayed at the crash site for about an hour.
Then he drove home. By the time Steve Wodka, Karen's friend and union contact, arrived at the crash site around 11 p.m., everyone was gone. The car had been towed, and all that was left was Karen's Kermagee paycheck in the mud. Eventually, Steve went back to his hotel.
And then, sometime after midnight, Trooper Fagan got a phone call from the local police department over in Crescent saying the Atomic Energy Commission wanted to inspect Karen's car for radioactivity.
Steve wasn't there, but here's what he's pieced together about that late-night inspection.
They open up the garage. And these three people show up. Well, only two of them were with the AEC.
The third was a Kerr-McGee representative. Fagan said the men spent about 20 minutes going through Karen's car, including her papers. They waved around a Geiger counter to check if anything was hot or contaminated. Steve thinks this would have given the Kerr-McGee employee the chance to look at every single piece of paper.
In order to survey things for plutonium, like a spiral notebook with 50 pages in it, you just can't just wand around. the top of it and say it's clean. You've got to go page by page by page to see if there's any contamination in it.
As Steve sees it, if someone from Kerr-McGee had discovered documents that were damaging to the company, then this would have given them the opportunity to disappear those documents. Poof. Gone.

Chapter 4: What were the findings of the Oklahoma State Highway Patrol?
Fagan tells me right off the bat that she fell asleep and went off the side of the road. I said, wait a minute, wait a minute, you don't understand. She was just on the highway for a few minutes.
Steve was suspicious. How could Fagan have reached this conclusion so quickly, less than 24 hours after she died? Why wasn't this being investigated more thoroughly? Steve tried explaining to Fagan that there was more to the story. Karen was on her way to a really important meeting. This idea that she'd fallen asleep, it didn't make any sense to Steve.
And I'll never forget Fagan saying, look, In my mind, she fell asleep at the wheel of the car unless you can prove it differently. And that started in my mind the fact that, now wait a minute, the fix is in. Something is going on here. How could this guy just shut the door in my face? He's supposed to be an investigating officer.
Steve became even more suspicious when he retrieved the box of Karen's things that had been recovered from her car. Remember, he'd been waiting for Karen to show up that night to meet the New York Times reporter. She was supposed to deliver the evidence she'd been collecting. Evidence that would support her allegations that Kerr-McGee was falsifying quality control reports.
Steve was eager to see if the papers he was looking for were among the belongings recovered from her car.
And we ripped the box open and went through everything and there was nothing in there about quality control.
The way Trooper Fagan described the documents was strange, too. Remember, three witnesses described seeing documents scattered around the crash site and how a patrolman gathered them up and put them in the car. Trooper Fagan later told an FBI agent that the night of the crash, he saw a thin red spiral notebook in the back of Karen's crushed car, along with two stacks of paper in the back seat.
And that description of two stacks of paper sounded off to Steve Watka.

Chapter 5: What did the FBI conclude about Karen Silkwood's death?
Now, this car had hit this concrete wing wall going 40 to 45 miles an hour. Silkwood was impaled on the steering wheel. But yet, he says there's these two piles of paper sitting on the back seat. It defies the law of gravity.
Another thing that didn't quite make sense? The red spiral notebook that both Fagan and Karen's co-worker Gene Young said they'd seen the night Karen died. The only papers in the box of things from Karen's car were notes from a union bargaining session. And there was something about the look of those papers that didn't add up.
This is a muddy craft site. There is this reddish Oklahoma mud on the left-hand driver's side of the car. You got these three guys sitting there, papers scattered all over the place. Not one piece of the papers that were given to us had any mud on them. No mud whatsoever on the stuff that was given to us.
Steve smelled a rat, and so he told his bosses that the union needed to hire its own investigator to look into the crash. That's where A.O. Pipkin enters the story. He'd analyzed thousands of crashes, including the one that killed Hollywood starlet and model Jane Mansfield. That was in 1967.
The union wanted A.O. Pipkin to see if the Oklahoma State Highway Patrol's version of events held up. So when A.O. Pipkin arrived in Oklahoma on November 16, 1974, he started assembling his puzzle pieces one by one. He inspected every inch of Karen's car. He walked the accident scene and measured Karen's tire marks on the grass. He read Fagan's accident report. He took photographs.
He drew diagrams. and he hired outside experts to review his work.
When he put all the puzzle pieces together, there were a few things that really stood out to him.
One, Karen's car had crossed the center line and veered off the left side of the road. Pipkin wrote in his report that typically, when a driver falls asleep at the wheel, they drift to the right, not to the left. That's because the road has a little peak or crown at the center. It slants so the rain will run off.
So that was his first takeaway, the way the car had gone from the right to the left-hand side of the road. That didn't mesh with the highway patrol's sleepy driver theory.

Chapter 6: How did Karen Pipkin Guerrero reflect on her father's investigation?
And Pipkin thought those particles could possibly have come from another vehicle.
And he thought other evidence suggested the presence of another car, too. When he examined the tire tracks Karen's car left in the muddy grass, he thought they suggested Karen had lost control of the car before it ever left the road. The car was rotating instead of tracking in a straight line.
And Pipkin wrote in his report that suggested, quote, either an impact by an unknown vehicle or a combination of an impact by an unknown vehicle and then driver overreaction and subsequent loss of control.
So Pipkin's puzzle was complete. And the picture he saw looked different from the Oklahoma State Highway Patrol's explanation of the crash. Here's what he told ABC about his findings.
In my opinion, and the people that I've had working with me, there's no circumstantial evidence there to indicate that somebody may, another vehicle may have hit the car in the rear.
Pipkin's evidence suggested that a second car could have hit Karen from behind. On November 18th, five days after Karen's death, Pipkin called Steve and his bosses to report his findings. He told them the same thing he later told National Public Radio.

Chapter 7: What new evidence emerged in the investigation of Karen Silkwood?
I did not believe that the accident was caused by Karen Silkwood falling asleep at the wheel. and the car just going off the road by itself.
Karen wasn't asleep. Pipkin's finding was explosive.
The LCAW immediately sent a telegram to the U.S. Attorney General and to the Atomic Energy Commission, or AEC, demanding an investigation.
Now, Oklahoma law enforcement and Kerr-McGee were the ones being looked at under a microscope. A higher-up in the Highway Patrol was assigned to reinvestigate the crash, a guy named Lieutenant Larry Owen. He doubled down on the conclusion that this was a one-car accident. And in January 1975, about two months after Karen's death, he also added a new detail.
Karen had been under the influence of drugs that night. Here's Owen in an interview with ABC.
I would either put her probably either totally asleep or in some state of stupor induced by the medication she was taking.
The medication? It was those Quaaludes Karen had been prescribed to help her sleep. The state medical examiner said that she was probably under the influence of them when she crashed. Fagan would later say in a deposition that two of Karen's coworkers had told him she'd been, quote, exhausted, unable to sleep, very fatigued.
And these co-workers both allegedly told Fagan they'd offered to drive her home that night.
But Fagan's account didn't square with another important eyewitness. As you heard earlier in the series, Karen's co-worker and friend Gene Young had also been at the union meeting that night. As far as we know, she was the last person to see Karen alive.
