The Lazarus Files: A Cold Case Investigation
by Matthew McGough

Hardcover

From the publisher's website:

On February 24, 1986, 29-year-old newlywed Sherri Rasmussen was murdered in the home she shared with her husband, John. The crime scene suggested a ferocious struggle, and police initially assumed it was a burglary gone awry. Before her death, Sherri had confided to her parents that an ex-girlfriend of John’s, a Los Angeles police officer, had threatened her. The Rasmussens urged the LAPD to investigate the ex-girlfriend, but the original detectives only pursued burglary suspects, and the case went cold.

DNA analysis did not exist when Sherri was murdered. Decades later, a swab from a bite mark on Sherri’s arm revealed her killer was in fact female, not male. A DNA match led to the arrest and conviction of veteran LAPD Detective Stephanie Lazarus, John’s onetime girlfriend.

The Lazarus Files delivers the visceral experience of being inside a real-life murder mystery. McGough reconstructs the lives of Sherri, John and Stephanie; the love triangle that led to Sherri’s murder; and the homicide investigation that followed. Was Stephanie protected by her fellow officers? What did the LAPD know, and when did they know it? Are there other LAPD cold cases with a police connection that remain unsolved?
