From the Dateline point of view, Sherri Rasmussen's murder illustrates the tenacity of detective work and the influence of advanced forensic technology. Sherri Rasmussen was 29 when she was gunned down to death in her Van Nuys condominium in Los Angeles on February 24, 1986.

Originally determined to be a potential burglary, further investigation uncovered that she had met her demise by design and at the hands of someone familiar to her, rather than a foreign intruder. Dateline storytelling has provided the intricacy of the case, that is, the contribution of DNA evidence to cracking the case after many decades.

The case went cold for over 23 years, largely due to initial assumptions, misplaced evidence, and the fact that the killer was a former LAPD detective. Breaking down the case with five important points gives us an idea of how investigators finally settled on Stephanie Lazarus and convicted her of justice, something often retold in segments on Dateline.


Here are 5 harrowing details about Sherri Rasmussen's murder, revisited by Dateline

1. Crime scene and initial investigation

Sherri Rasmussen was discovered at her residence having sustained a gunshot wound that had been initially determined to be the manner of death. There was also evidence of struggle, including overturned items of furniture and shattered glass. There was some initial mention of defensive wounds, but these were for the struggle before she was shot.

The researchers first suspected the crime as a burglary, describing an appearance of ransacking. Yet no jewelry and valuables were disturbed, indicating staging. Dateline reporting has pinpointed these anomalies, illustrating how initial misinterpretation resulted in the belated identification of the actual perpetrator.


2. DNA evidence in the bite mark

The most material forensic evidence was a saliva sample from the bite mark on Rasmussen's arm. It had been saved, and technological improvements later permitted the gathering of a genetic profile. The DNA was that of a female donor, eliminating the notion of a male burglar.

This recovered sample was part of what connected Stephanie Lazarus to the crime. Even though bite mark analysis as a science is suspect at times, in this instance, it was the DNA found in saliva that was the clincher. Dateline has covered this as part of the way in which cold-case crimes are being solved using new forensic technology.


3. The offender: Stephanie Lazarus

Stephanie Lazarus, a former LAPD detective, was eventually found to be the murderer of Rasmussen. Lazarus also had a history of dating Rasmussen's husband, John Ruetten. Investigators viewed jealousy and personal motives as the greatest factors in the crime.

Her history as a retired police officer was the reason the suspicion was lagging. Dateline has looked into the reason why this made it impossible to investigate, emphasizing the fact that perpetrators in the police force can go unnoticed for years.


4. Reopening the cold case

The crime remained unsolved until 2009, when Detective Jim Nuttall re-examined the evidence, questioned the initial hypothesis of burglary, and made a list of potential suspects. DNA from a used coffee cup litter found in the investigation was compared with the saliva from the bite mark, proving Lazarus's culpability.

This reopening calls to mind the importance of forensic investigation and verification in cold cases. Dateline coverage emphasizes the investigative techniques and re-examination of evidence that were essential in solving the case more than two decades after the murder.


5. Trial, conviction, and parole status

Stephanie Lazarus was arrested in June 2009, indicted, and convicted of first-degree murder in 2012. She was sentenced to 27 years to life in prison. Trial proceedings focused on DNA evidence, motive, and crime staging.

As of now, Lazarus is still behind bars at the California Institution for Women. While she has been made parole eligible, she has yet to be let out. Dateline has covered both the trial and the implications of a law enforcement officer being capable of having committed such a crime, including the added burden of slow justice and cold-case cases.


The Dateline case of Sherri Rasmussen illustrates some of the key features of criminal investigations: meticulous scrutiny of the crime scene, significance of forensic evidence, difficulties of reviving cold cases, and judicial process for exceptional law enforcement officer-related cases.

In order to return to these five critical facts, the crime scene, DNA evidence, perpetrator, cold case investigation, and trial verdict give the whole picture of the investigation and eventual conviction. The case is appropriate for forensic ingenuity, investigative tenacity, and criminal justice, and is a standout case in both true crime journalism and the Dateline program.
