SANTEE, Calif. — The San Diego County Sheriff’s Department on Sunday revealed the identities of the two men who died Friday night in a murder-suicide in Santee.

The initial shooting happened after 7 p.m., when Sheriff’s deputies responded to the 8800 block of Diamondback Drive after receiving a report that a man had shot another man, Lt. Thomas Seiver said in a news release.

A block away, deputies spotted a car matching the description of the one belonging to the suspected shooter and pulled the driver over, Seiver said. When deputies approached the vehicle, they found the man had shot himself dead. The San Diego County Medical Examiner’s office identified the man as 42-year-old Daniel Wayne Isaac.

Isaac’s autopsy revealed a gunshot wound, with his manner of death being suicide, according to the medical examiner’s office. He lived on Diamondback Drive.

When deputies responded to where the initial shooting was reported, they found a man with multiple gunshot wounds inside a garage, Seiver said. The medical examiner’s office identified the homicide victim as 36-year-old Wesley Aaron Devault, a San Diego resident.

Homicide detectives say Isaac is suspected of killing Devault. Devault and Isaac were acquainted, but motive and further circumstances were under investigation, Seiver said.
