The Case Goes Cold
June 3, 1981
“God damn, will you find me? I just stabbed somebody with an icepick. I can’t stop myself. I keep killing somebody.

Kimberly Compton (https://morbidology.com/the-weepy-voiced-killer-paul-michael-stephani/)
Real or a Prank Call?
- The dispatcher initially thought it could be a “sick prank”
- Unfortunately, it was no prank
- That same day (1), 3 teenage boys came across a bloodied body near a freeway construction site in St. Paul
- They realized that the call wasn’t a prank because it had accurately identified the murder weapon
- She had been stabbed 61 times with an icepick
- The body was identified as Kimberly Compton
- 18
- Recent college graduate
- Had just moved from Wisconsin to the Twin Cities (Minneapolis and St. Paul) for a job
- Had literally arrived on the bus an hour and half before she was killed
- Last seen at Mickey’s Diner in Minneapolis where waitresses remembered her coming in and being approached by a man
- She told the man she was new to the area and he offered to take her on a tour of the city
- She accepted and they left the diner together

Another Call
Let’s break it down:
“Don’t talk, just listen. I’m sorry for what I did to Compton, I couldn’t help it. I don’t know why I had to stab her. I am so upset about it. I keep getting drunk every day, but I can’t believe I did it, it’s like a big dream. I can’t think of being locked up, if I get locked up I’ll kill myself. I’d rather kill myself than get locked up. I’ll try not to kill anyone else.
A Lead?
- Police were able to trace the call to a payphone at a bus station
- By the time police got there the caller was already gone
- The next day, the newspaper got a call from the perpetrator correcting them on details they had printed about the case
- Despite his inability to keep his mouth shut, police still had no idea who the mystery caller was and he became dubbed the “weepy voiced killer”

Connecting the Calls
- Since the caller had such a distinctive voice, investigators decided to listen to the station’s backlog of recorded calls and were able to make the link to the call made after the attack on Karen Potack
- A portion of the phone calls were released to the public in an attempt to find someone that could help identify the voice
- It was a long shot and unfortunately didn’t result in any new leads
A Confession
Only 2 months after Kimberly’s death, in August of 1981, a confession was made. Alan Lopez was holding his family hostage and during negotiations, he confessed to Kimberly’s murder.
It turned out he had a history of mental illness and assault. He ended up taking his own life and the calls stopped.
The End?
