The Detective Who Was Secretly a Killer | Stephanie Lazarus Case
In 1986, a young woman was murdered inside her own home in Van Nuys, California. At first, investigators believed they were looking at a burglary that had turned deadly. But beneath the surface, the crime scene contained clues that would remain unexplained for more than two decades.
The victim was 29-year-old Sherri Rasmussen, a successful hospital nursing director who had been married to John Ruetten for only a few months. She was found dead after a violent struggle, and investigators discovered evidence that suggested the crime may have been staged to look like a robbery.
Among the most important pieces of evidence was a bite wound found on Sherri's arm.
At the time, forensic technology couldn't provide investigators with the answer they needed. The evidence was preserved, but the case eventually became a cold case.
For years, Sherri's family continued searching for answers while the investigation remained unresolved.
Then, more than two decades later, advances in DNA testing gave investigators another opportunity to examine the evidence.
The results would lead them in a shocking direction.
Instead of pointing toward an unknown intruder, the evidence eventually connected the investigation to Stephanie Lazarus, an LAPD detective who had spent years working within the same department responsible for investigating the murder.
But investigators couldn't simply reveal everything they knew.
Instead, they invited Stephanie into an interview room and began asking questions about the case.
What she didn't know was that detectives had already taken steps to obtain DNA evidence connected to her.
The interview became a fascinating example of how experienced investigators can use patience, conversation, and carefully planned questioning to uncover information from someone who believes they're simply helping with an investigation.
This video takes a closer look at the Sherri Rasmussen murder, the decades-long investigation, the DNA evidence that changed the case, Stephanie Lazarus's connection to the victim's husband, and the interrogation that eventually led to her arrest.
The case would ultimately end with a first-degree murder conviction and a lengthy prison sentence.
Decades after the original crime, the evidence that had once seemed almost useless became one of the most important pieces of the entire investigation.
This is the story of how a decades-old cold case was finally brought back to life—and how a detective who spent years questioning suspects eventually found herself on the other side of the interrogation table.
Watch until the end to see how investigators connected the evidence, reopened the case, and confronted Stephanie Lazarus with what they already knew.
