Los Angeles, CA
In 1986, Sherri Rae Rasmussen, a nursing director, was beaten and shot to death in her home. No one was taken into custody and the file sat open until recently when detectives started going back into some cold cases. DNA testing revealed that the killer was a woman, which surprised everyone because the thought at the time was that a couple of unidentified burglars who were operating in the area at the time had killed her.
When that broadened the search, detectives realized that they knew someone who had been in a relationship with Rasmussen's husband at the time. They put a tail on her, got hold of something with her saliva and ran a DNA test.
Which turned out to be a match.
Unfortunately, the suspect is one of their own, Detective Stephanie Ilene Lazarus, 49.
Lazarus was arrested this morning downtown at Parker Center on suspicion of murder. No word on formal charges or, well, anything else, yet.
