Via SDPD: On December 20, 2021, just before 8:30 p.m., the San Diego Police Communications Center received a call requesting a welfare check on a neighbor at 3600 Mount Abbey Avenue in the Clairemont Mesa West area.
Officers from Northern Division arrived at the location and contacted a disoriented elderly male in the garage. The vehicle inside the garage was running and the garage was filled with exhaust fumes. The home was also filled with the odor of natural gas.
During a check of the residence, an obviously deceased female was found inside. It was unknown when or how the female died, but she had been deceased for some time.
Due to the suspicious nature of her death, San Diego Police Homicide Detectives were called to the scene and began investigating the incident. Although the investigation continues, detectives have no information about the circumstances surrounding the woman’s death. Detectives are collecting evidence and attempting to locate witnesses.
