The Mystery of Jane Mixer

Thu, 20 Mar 2025

Description

In 1969, Jane Mixer was attending the University of Michigan Law School when she was found dead just miles from her dorm. She had been shot twice in the head and strangled. Jane was the third of seven young women to be found dead in the area within two years. Investigators believed John Norman Collins was the serial killer responsible for several of the murders but couldn't prove he killed Jane. The case went cold until 2001 when the investigation was re-opened by testing DNA evidence collected more than 30-years earlier. “48 Hours" Correspondent Maureen Maher reports.

Chapter 1: Who was Jane Mixer and what happened to her?

47.219 - 73.808 Maggie Nelson

She had been shot once in the front and once in the back of the head. Here is just where he dumped her on a night of cold rain. Jane was a silent but very strong presence growing up. I had a lot of unanswered questions, both about Jane's murder, about who she had been. I look back to 1969 to find out.

0

83.19 - 91.957 Barbara Nelson

She was bright and articulate and concerned and empathetic. I mean, she stood up for what she thought was worth saying.

0

91.977 - 99.103 Detective

One of the first women admitted to the University of Michigan Law School. Very promising future ahead of her, and her life was stolen.

0

104.267 - 112.154 Barbara Nelson

She was on her way home for a weekend. She was picked up supposedly at 6 o'clock by someone who was going to give her a ride to Muskegon, Michigan.

0

113.877 - 137.29 Detective

She gets into the vehicle with him, expecting to head west. And we've got a certain number of hours where Jane's basically missing. In the early morning hours, March 21, 1969, Jane's body was discovered in the Denton Road Cemetery.

139.391 - 142.053 Maggie Nelson

My aunt was shot twice in the head and strangled.

145.209 - 170.149 Barbara Nelson

My name is Barbara Nelson, and my sister was Jane Mixer. I think I didn't want to even get close to what had happened to her. At the time of Jane's death, there were a whole series of murders of young women. They did arrest a man for the murder of one of the young women, and he was tried and convicted.

Chapter 2: What was the initial investigation into Jane Mixer's murder?

172.233 - 181.66 Maggie Nelson

For many years, most people thought my aunt was the victim of a serial killer. When I did my research, I was not convinced that Collins killed my aunt.

0

182.16 - 189.726 Detective

Jane's case was just too different. The fact that she was placed in that cemetery with her belongings, very unlike the other cases.

0

191.307 - 195.67 Maggie Nelson

There were many mysteries. I had reasons to think that somebody was still out there.

0

198.453 - 201.515 Detective

I certainly felt that someone had gotten away with murdering Jane.

0

202.17 - 207.333 Barbara Nelson

I never in my wildest dreams thought things would happen as they did. Never, ever.

215.297 - 216.318 Narrator

Deadly Ride.

228.123 - 242.395 Maggie Nelson

Jane was both an inspiration of many things I wanted to be, driven, disobedient, brilliant, independent. And I also knew that she died horribly.

243.136 - 258.59 Maureen Maher

Jane Mixer was murdered in Ann Arbor, Michigan in March 1969. She was 23. About the same age her niece, Maggie Nelson, was when she resolved to learn all she could about the aunt she never knew.

258.61 - 278.395 Maggie Nelson

I didn't feel as though I could ask anyone in my family the details about Jane's murder. What was it that you wanted to know, that you needed to know? The questions weren't so much. I mean, they were like, who was she? How did she die? But they were really also, why does this story haunt me so much? We didn't talk about what had happened to Jane.

Chapter 3: Why was John Norman Collins suspected and what was his fate?

Chapter 4: How did Maggie Nelson research her aunt's life and death?

657.061 - 667.808 Mary Catherine

You would see these photographs each time a body was found, you know, all lined up with dramatic headlines. Catherine Ramslin teaches and writes about forensics.

0

667.988 - 678.654 Maureen Maher

This is one of the better maps of where each of the murder victims have been found. Her latest book is about serial killers. Back in 1969, she was living near Ann Arbor.

0

678.854 - 688.107 Mary Catherine

They have young women being murdered and nobody can find the guy and stop him. That's just something that had never happened here.

0

689.244 - 694.885 News Reporter

Karen Sue was dead, the victim in the seventh unsolved murder of college co-eds.

0

694.925 - 708.368 Maureen Maher

As body after body was recovered, the Mixer family retreated. We were buried within our own little worlds of pain and didn't talk about what was really going on. But the community was clamoring for action.

708.608 - 714.289 Mary Catherine

We're afraid we might be the next one. You never know. He's out there. He's a monster. He's a madman.

715.325 - 721.579 Detective

How long can you have young women being killed before the pressures become so great because you as the police can't solve this?

726.492 - 731.816 Narrator

In 2020, a group of young women found themselves in an AI-fuelled nightmare.

732.156 - 739.041 Unidentified Speaker 2

Someone was posting photos. It was just me naked. Well, not me, but me with someone else's body part.

Chapter 5: What new evidence emerged in the investigation decades later?

1374.864 - 1375.484 Gary Leiterman

No, I did not.

0

1376.164 - 1381.726 Maureen Maher

Although the police kept grilling Leiterman, he stuck to his story. Why didn't you believe him?

0

1382.106 - 1382.846 Detective

Primarily the DNA.

0

1383.775 - 1404.108 Maureen Maher

The police lab could not pinpoint where the DNA came from, but said it was not blood and not semen. It might be something like sweat, saliva, or skin cells. It was enough for police to accuse Leiterman of murder. A 35-year-old murder. What went through your mind?

0

1404.728 - 1415.361 Gary Leiterman

They were wrong. I did not do this. My concerns for my family and what this was going to do to them. Just the accusation is horrible.

1416.822 - 1418.703 Maureen Maher

Leiterman was taken into custody.

1418.723 - 1426.868 Gary Leiterman

Detective Schroeder had put me on the phone with my wife while she was in the car. I could hear the anguish, the terror in her voice.

1427.368 - 1435.633 Maureen Maher

At the time, Leiterman's wife was too distraught to speak with us, so their close friend Rachel Kuby stepped in to talk about the man she has known for three decades.

1436.933 - 1444.768 Rachel Kuby

I believe they've got the wrong man. It just isn't Gary. And the Gary I know wouldn't have done this.

Chapter 6: Who is Gary Leiterman and why was he accused of Jane Mixer's murder?

1449.151 - 1454.675 Gary Leiterman

My personal life was pretty much wrapped up with my family, taking vacations with them, dragging the kids along to Civil War battlefields.

0

1455.037 - 1481.338 Maureen Maher

But he did have one scrape with the law in 2001, when he was caught writing himself fake prescriptions. He had become addicted to painkillers during a bout with kidney stones. He was ordered to a treatment program, which he successfully completed. But his DNA was put in a database. And that is how he now finds himself accused of murder. Did you kill Jane Mixer? No, I did not.

0

1482.028 - 1486.249 Maureen Maher

Did you take her body to the cemetery and dump her there? Were you with anyone who did that?

0

1486.749 - 1488.15 Gary Leiterman

No, I was not. No, I did not.

0

1488.25 - 1489.77 Maureen Maher

Did you have anything to do with the murder?

1490.371 - 1490.631 Gary Leiterman

Nothing.

1491.331 - 1500.614 Maureen Maher

Prosecutor Stephen Hiller doesn't buy that and believes Leiterman should pay for this crime. What would be the motive for him to kill a woman?

1501.234 - 1510.977 Prosecutor

The fact that her pantyhose had been taken down, her jumper had been pulled up so that her genitals were exposed. I think that it's fair to conclude that the motive was sexual assault.

1511.843 - 1520.232 Maureen Maher

But there was no physical evidence of sexual assault. And that is just one of the many challenges Hiller faces in this old case.

Chapter 7: What challenges does the state face in prosecuting Jane Mixer's case?

1629.23 - 1631.851 Barbara Nelson

There are enormous mysteries that remain in this case.

1640.503 - 1655.889 Jake Brennan

Do you know about Jerry Lee Lewis wanting to murder Elvis? Or the hip-hop star who cannibalized his roommate? What about the murders ACDC was blamed for? Or the suspicious deaths of Brittany Murphy and River Phoenix? Or about Anthony Bourdain's wild lust for life and untimely demise?

All rise, please. The Honorable Donald E. Shelton presiding.

0

1682.723 - 1689.51 Maureen Maher

Michigan prosecutor Stephen Hiller says Gary Leiterman got away with murder for 36 years.

1689.97 - 1695.896 Unidentified Speaker 2

Jane Mixer's death remained unsolved until August of 2004.

1696.396 - 1699.679 Maureen Maher

A lot of the evidence was saved from this crime scene, correct?

1700.8 - 1701.341 Unidentified Speaker 2

We got lucky.

1702.208 - 1709.051 Maureen Maher

Now in 2005, Leiterman is on trial for the 1969 murder of Jane Mixer.
