Sherri Rasmussen called in sick to the Glendale hospital where she worked on February 24, 1986. Her husband, John Ruetten, and her sister tried calling her during the day. When John got home that evening, Sherri’s BMW was missing and glass from a broken door was on the driveway. He found Sherri dead inside. She was twenty-nine. [1] [2]

What was left in the home

Stereo equipment had been stacked near the garage and a drawer had been emptied. Other valuables were still there. Police first pursued a burglary theory. They found the BMW a short distance away in March, with the keys still in the ignition. Years later a prosecution analyst argued that the disarray had been arranged to suggest a theft. [1]

The examination established that Sherri had been shot and documented what appeared to be a bite injury on her arm. A criminalist saved swabs from the injury. In 2005, a lab recovered a major female DNA profile from one of those swabs. A national database search turned up no match. Investigators still had a profile they could compare with a sample from someone they identified separately. [1]

A cup, a straw and a second comparison

Stephanie Lazarus had known John before he married Sherri. A witness described a confrontation between Lazarus and Sherri at the hospital where Sherri worked. By the time detectives revisited that history, Lazarus was a detective in their own department. Investigators recovered a cup and straw she discarded. The usable part of the profile from those items matched the major profile from the arm swab. [1]

A known sample from Lazarus later matched the profile at all thirteen locations the first lab had tested. An independent lab used a second swab from the injury and found a match at fifteen locations. The genetic comparison came from material collected at the injury. The medical evidence about when Sherri sustained it helped explain why that particular sample mattered. [1]

The verdict and the parole hearings

Detectives questioned Lazarus on June 5, 2009, and arrested her. A jury convicted her of first-degree murder in 2012. She received twenty-seven years to life. The California Court of Appeal affirmed in 2015 and upheld the admission of the interview after considering the circumstances in which detectives questioned her. [1] [2]

Lazarus acknowledged killing Sherri at a November 2023 parole hearing, and a panel recommended release. That decision was rescinded in October 2024. A panel denied parole in February 2025, and another did so on October 9, 2026. By then Sherri’s sisters and her widower had taken their account of the loss to the parole board as well as to the court. [3] [4]
