“Friendly” Cop Has No Idea Police Already Matched Her DNA After 23 Years

Overview

The video recounts how the LAPD homicide case of Sherri Rasmussen—murdered in 1996 in Van Nuys—was solved decades later using DNA evidence tied to LAPD detective Stephanie Lazarus.

Cold case background and key forensic lead

• On February 24, 1996, Sherri Rasmussen was found shot three times after a violent struggle in her home. The crime scene initially appeared to be a botched burglary.
• Investigators observed a distinctive semicircular bite mark on her left forearm and collected a swab from it.
• For 23 years, there was no arrest, and the case stalled.

Breakthrough: bite mark DNA points to a police officer

• In 2009, a cold case detective compared the bite-mark DNA from the evidence against a national database.
• The match implicated Stephanie Lazarus, an LAPD detective with decades of service.

The interrogation deception and the attempt to secure DNA

• Investigators reportedly did not immediately tell Lazarus she was a suspect. Instead, they used conversation and “privacy” to get her to speak freely.
• During the interview, Lazarus repeatedly claimed she didn’t remember or couldn’t confirm key details about any confrontation with Sherri.
• Investigators also sought a fresh buccal swab from Lazarus. When she realized the implications, she asked for a lawyer.
• The video claims investigators had already conducted earlier DNA testing—reportedly by collecting DNA from something she discarded during surveillance. That earlier testing reportedly did not match the bite-mark DNA and fingernail cells, so the later swab request is described as a formal/confirmatory step.

Why the case against her strengthened over time

Investigators developed a narrative tying Lazarus to both the victim and motive, including:

• Lazarus and Sherri’s husband, John Rutten/Ruuton (names appear inconsistently in the subtitles), had known history from UCLA years earlier and maintained an ongoing relationship dynamic.
• The video describes claims and testimony (from colleagues/witnesses and friends) that Lazarus interfered with John’s relationship with Sherri, including:
  • confrontations at Sherri’s work
  • later allegations that Lazarus threatened Sherri with “if you can’t have John, nobody would.”
• Investigators allegedly uncovered property/weapon-related information:
  • Lazarus filed a robbery report shortly after Sherri’s murder involving a .38 revolver (Smith & Wesson Model 49)—the same caliber associated with the killing—without earlier connections between the documents being recognized.

Additional investigative gaps and re-examination

• The video notes evidence-handling issues and missing records over the years, including:
  • disappearance of certain biological material
  • missing earlier interviews (including John and Sherri’s father)
• A 2005 step is highlighted where an analyst discovered the bite-mark swab had been missing, but later found it recovered from a coroner’s freezer and preserved well enough to use.

---

Trial outcome and sentencing

• Prosecutors argued Lazarus murdered Sherri as a planned sequence, not a robbery, relying on DNA evidence and broader circumstantial reconstruction.
• The video states the jury convicted Lazarus in March 2012 of first-degree murder (with deliberations lasting less than a day).
• Sentence: 27 years to life, with parole eligibility noted for 2034 (age 74).
• The video further states that in a later hearing (mentioned as November 2023), Lazarus admitted to killing Sherri but claimed she did not go to the condominium intending to commit the murder.

Current status (as presented)

• As of the latest information cited in the subtitles, Lazarus remains in custody at the California Institution for Women in Corona.
• The murder weapon was never recovered, but DNA ultimately identified her.
