El Paso, Texas (KDBC) — Police are one clue away from solving a 40-year-old murder mystery.
They're hoping you can help close the case.
El Paso Police Detective Michael Aman took me to the scene of the crime and carefully explained the details of the murder.
After the walkthrough was over, I was left with Goosebumps knowing there is only one key piece of evidence missing, and that piece could finally solve this crime.
"She told him, I'm being raped. That's all the opportunity she had to say it," Detective Aman said as he recounted that chilling moment.
September 1973. That's when 18-year-old Susan Wilson's life came to a frightning end, at an eastside apartment complex.
"It happened in the building behind me closest to Montana, and in apartment H which is on the second floor,” said Detective Aman.
On that day, a mailman had stopped by to deliver a package to Susan's apartment, and that's when he heard pleas for help.
"The door opens just a crack, so he had the opportunity to see the victim,” said Detective Aman describing the disturbing facts. “She was standing up, part of her clothing was undone, was missing and it appeared as if her hands were tied behind her back.”
According to Detective Aman, the mailman tried opening the door, but to no success.
"He announced in a loud voice that he was going to call the police,” Detective Aman said. “He went down the stairs and came right here where I am standing. There used to be a phone booth, until a few years ago."
Police rushed to the scene, but the suspect was gone, and Susan was dead.
"Police found the victim had been stabbed to death and her throat had been slashed,” he said.
Aman said there is still hope in this case: one large piece of the puzzle.
And locating that piece could help finally close this case.
That one missing piece is a light blue Volkswagen station wagon.
Last Aman checked, there were only 120 registered in El Paso at the time.
"The car was never found, the driver was never found,” he said. “We've been trying to identify that car. I've been working really hard and spent a lot of time trying to identify that car.
Aman added that there is another similar case from 1973 that could possibly be related, but he remains focused on solving Susan’s murder.
Aman said besides the car, he also has Susan’s apartment door as evidence for further investigation.
All he needs is that one tip that could lead to the end of this 40-year-old mystery.
