Attempted Murder and Felony Elder Abuse - Spring Valley 

October 14, 2026 – San Diego County Sheriff’s Office officials report that on Tuesday, October 13, at about 12:20 a.m., deputies from the Rancho San Diego Sheriff's Station responded to a report of an assault with a deadly weapon at an independent living facility located in the 900 block of Sacramento Avenue in Spring Valley.

Upon arrival, deputies contacted the 65-year-old victim who sustained serious injuries after being struck over the head with an aluminum bat after an argument with the suspect, Jennifer McCoy (40). The victim was immediately transported to the hospital via ambulance. McCoy barricaded herself inside of her bedroom with the bat and refused to come out.

Numerous attempts were made by deputies to de-escalate the situation and gain compliance from the suspect, but she refused to come out. The Sheriff's Elder Abuse Unit was activated and responded to the scene.

Due to the suspect's unwillingness to comply, the Sheriff's Crisis Negotiation Team (CNT) and Sheriff's Special Enforcement Detail (SED/SWAT) were called to assist.

Just after 5:15 a.m., McCoy was taken into custody with the assistance of a Sheriff's K-9. McCoy was transported to a hospital for treatment and will be booked into the Las Colinas Detention and Reentry Facility on felony assault charges.

The Sheriff's Elder Abuse Unit will assume primary investigative responsibility for this case.
