319. The Killer Next Door - The Murder of Leslie Peer

This episode of *Murder With My Husband* investigates the 2001 murder of Leslie Prier, a beloved mother and wife in Chevy Chase, Maryland. Initially, her husband Carl Sandy was the prime suspect due to a bloody crime scene, inconsistent alibi, failed polygraph, and marital strain. However, DNA evidence under Leslie’s nails did not match Sandy, and no other suspect emerged—leaving Sandy as a lifelong social pariah despite his innocence. The case went cold for over two decades until 2022, when Montgomery County’s cold case unit reopened it using genetic genealogy. By analyzing DNA from the crime scene and building a family tree, investigators traced the unknown male DNA to Eugene Gilgore, Leslie’s former high school boyfriend. Though Eugene had no prior criminal record, his history of addiction, violent behavior toward ex-wives, and access to the Prier home through his brother’s dog-sitting role made him a credible suspect. In 2024, Eugene was arrested and, after DNA confirmation, pleaded guilty to second-degree murder, citing a drug- and alcohol-induced blackout. He was sentenced to 22 years in prison, though he offered no motive, leaving lingering questions about his true state of mind and whether the full truth will ever be known. The episode ends with a cautionary message about jumping to conclusions in true crime, especially when the husband is the first suspect.
