On December 2, 2019, 66-year-old Cynthia Kilough was shot and killed at her home in Big Bear Lake, California. Her roommate, Jeffrey Tiner, was also killed in the same incident. A third roommate, Ralph Meneses, called 911 to report the shooting and told dispatchers he had been attacked by Kilough and Tiner before he shot them. Kilough was found outside the home with gunshot wounds, transported to a local hospital, and pronounced dead on arrival; Tiner was found deceased inside the residence.

Meneses suffered several puncture wounds that were later determined to be self-inflicted. He was arrested and charged with murder and held without bail at the Central Detention Center. A GoFundMe organized by Leanna Kilough was set up to help the family with funeral expenses.

The investigation is ongoing; anyone with information is asked to come forward.
