When the tragic murder of 29-year-old nursing director Sherri Rasmussen shook Los Angeles in February 1986, public attention immediately focused on her newlywed husband, John Ruetten. They had been married for just three months when Ruetten returned to their Van Nuys townhouse after work and discovered his wife dead on the living room floor. For decades, the case languished as a botched investigation before DNA technology exposed a staggering truth: Sherri had been murdered by Stephanie Lazarus, an LAPD officer and Ruetten's former college lover.
Today, decades after the conviction and trial that gripped the nation, public curiosity persists around what happened to John Ruetten, how he navigated the fallout of the investigation, and where his life stands now. Understanding his path requires cutting through internet rumor and examining the verifiable record of how a grieving husband rebuilt his life away from the public eye.
The 1986 Tragedy and Initial Police Investigation
On February 24, 1986, Ruetten left for work as an engineer, leaving Sherri at their condominium. When he returned between 6:00 and 7:00 PM, he found the gruesome crime scene. Initial responding officers and lead detective Lyle Mayer treated the incident as a botched burglary, overlooking crucial clues and dismissing concerns raised by Sherri's parents regarding an intense, harassing ex-girlfriend from Ruetten's past.
During the initial interviews, Ruetten cooperated with police, submitted to polygraph examinations, and provided a verifiable alibi placing him at his workplace. Investigators quickly cleared him of direct involvement in the homicide. However, the shadow of suspicion lingered in true crime forums and media retrospectives for years, with critics questioning why investigators failed to scrutinize Lazarus sooner given her explicit journal entries and letters expressing profound jealousy over Ruetten's marriage.
Uncovering the Truth: The 2009 Cold Case Breakthrough
The case remained cold for 23 years until cold-case investigators Jim Nuttall and Paul Coulter reopened the files in 2009. Re-examining the physical evidence led to forensic testing of saliva recovered from a bite mark left on Sherri's arm during the violent struggle. The DNA profile matched Stephanie Lazarus, who by then had risen through the ranks to become an LAPD detective.
During the subsequent 2012 trial, prosecutors detailed how Lazarus harbored an obsessive, unrequited fixation on Ruetten, viewing Sherri as an obstacle. Ruetten testified during the trial, acknowledging his past romantic history with Lazarus and admitting they had contact prior to his marriage, though he maintained he never considered her a serious partner after moving on with Sherri. Lazarus was ultimately convicted of first-degree murder and sentenced to 27 years to life in prison.
John Ruetten's Life After the Trial
Unlike public figures who court media attention following high-profile legal battles, John Ruetten chose a path of absolute privacy. Following the 2012 conviction and subsequent civil wrongful death judgments secured by Sherri's parents, Nels and Loretta Rasmussen, Ruetten retreated entirely from public view.
- Relocation and Career: Ruetten stepped away from the southern California region where the tragedy unfolded, moving out of state to pursue a quiet, private professional career in engineering and technology consulting.
- Media Silence: He has declined all interview requests, documentary appearances, and book proposals, refusing to commercialize the tragedy or his private life.
- Personal Boundaries: Friends and legal associates from the trial era have consistently reported that Ruetten sought anonymity to heal and allow subsequent generations to move forward unburdened by the historic notoriety of the case.
According to archival reporting by publications like The Atlantic, Ruetten's cooperation with cold-case detectives was instrumental in providing background context during the 2009 revival of the investigation, even though his early interactions with original detectives had been poorly documented.
