Happy holidays, listeners! We're starting off our winter break by bringing you an episode from our colleagues at Science Vs about how a notorious murder case was solved with help from an unlikely source: a nuclear weapons lab. It’s the 1990s at a medical center in California, and patients are dying. At first, this doesn’t seem strange — it’s a hospital, and deaths happen. But then rumors start to circulate about a particular health care worker: difficult or needy patients in his care are ending up dead. The cops get involved, but there’s a huge problem: there’s no hard evidence. Until the so-called “Lab of Last Resort” steps in. Crime Junkie host Ashley Flowers joins us as we speak to analytical chemist Armando Alcaraz, former Detective Sergeant John McKillop, and Dr. Ian Musgrave.

Chapter 1: How did a nuclear lab help catch a serial killer?
Welcome to Science Versus. Hello. I'm so excited to be here. So something that a lot of people might not know about you is that you graduated from biomedical science. That was your degree. It was. And we are twinsies.
We both have this degree. I thought I really wanted to be a doctor when I was young. And I was... I think fortunate enough to have to work full time to put myself through school. And I worked at a hospital for all five years and went to school at night. And I got to work side by side with residents who you have to be before you're a doctor. And I was like, oh, that's not the life I want.
Right.
I made a bit of a pivot, and I finished my degree with actually a focus in research. And so what do you like about science? I like facts, and I think so much in life can be so subjective. And what I love about science is it feels like there are real answers and not just opinions. Like sometimes things get to be black and white, and that's not very often do you get that. Yeah.
Yes. Yes. I think that's one of the reasons I love science too. It's a way to understand the world. Yeah. If science is your side piece, I guess, your true love is really mysteries.
Yes.
That I've heard you say that you are obsessed with solving mysteries. Obsessed. What is it about a mystery that just grabs you and you cannot let go?
I think I'm just overall like a very curious person, the more that I've like really drilled into it. And I want to, I want the answers to everything. The universe, I want the answers to all the unsolved mysteries, like give them to me.
Well, today we have a real mystery for you and it's got a whole bunch of science in it. So should we jump in?

Chapter 2: What were the suspicious circumstances around the hospital deaths?
But for this case, I mean, John says that they were specifically looking for victims who were getting better. You know, like you said, who were toasting New Year's, who wanted to live. And in that confession room, Efren told John that there was a completely different reason for doing what he did.
He would get irritated that he would have to go tend to a patient. So bottom line with him was patients were irritants. They disrupted his day. You know, patients in the hospital are very needy and clicking that button a lot. And so he confessed to killing because of workload.
Yeah.
What? Yeah. He told the police that, quote, it was not something that gave me joy. And then he said, quote, only when I was only at my wits end on the staffing, I'd look at the board, who we got to get rid of. What? So callous. We talked to Sarah, our science journalist, about the victims.
There was one woman who actually survived the attempt because he didn't give her enough and she pressed the call button too much and annoyed him. And so he dosed her.
There's, like, that doesn't even, like... That doesn't even, like, register. I just... Like, can someone be that cold? It almost would make more sense if he...
you know did like get some kind of like joy or something from the actual killing like that almost makes more sense to me than just being like well too many people today so like which one's gonna lose their life so we can like have a manageable schedule yeah evan took a plea deal and was eventually convicted of killing the six patients that armando and his colleagues found pavillon in
Efren was sentenced to six consecutive life terms without the possibility of parole for the murder counts and 15 years to life for the attempted murder of Jean Coyle, who was the woman who survived. And there is this extra weird twist to this story, Ashley, because if Efren had gone to trial instead of taking a plea deal, he might have been faced with the death penalty.
And at that time, if he got the death penalty, do you want to guess? They would have used the same drug. Yes. One of the drugs that they would have used to kill him was Pavalon. Wow. So, Ashley, that's the case of how some nerds used some smooth and beautiful moves to catch a killer.
