Deputies discovered the man on a hillside north of Dehesa road around 6 p.m. Monday while responding to a call from a citizen who spotted a blinking light and thought it was coming from a hiker in distress.
Instead, deputies said they found a vehicle that belonged to a person of interest in a homicide earlier in the day.
Local law enforcement officers were on the lookout for a 2004 maroon Chrysler Crossfire with the California license plate 5MFB596 in connection with the stabbing death of Caridad Hendrix. She was found dead in a bedroom of a home on Monette Lane around 6 a.m. Monday. Her husband, Marquin Anthony Hendrix reported the crime to a relative, according to San Diego police officers.
In Alpine, deputies started searching the area for the driver of the abandoned car and found a man in an enclosed carport on Hawks Vista Lane, just west of Tavern Road. The man approached deputies carrying a shovel deputies said.
After ignoring repeated commands to drop the shovel, deputies opened fire.
The suspect was struck an unknown number of times and pronounced dead at the scene.
The name of the suspect is being withheld until family can be notified.
Sheriff's investigators believe the man may be Marquin Anthony Hendrix but are waiting for confirmation from the county's medical examiner.
"Before we say with any certainty, we want to make sure it is in fact him," Lt. Dennis Brugos told NBCSanDiego.
