A neighborhood in Costa Mesa remained locked down on Monday after the discovery of a body of a man who neighbors said blew himself up outside his home.
The incident happened at 8 p.m. Sunday in the 3100 block of Bermuda Drive near Labrador Drive.
Someone noticed a man on the ground in a front yard and called an ambulance.
The man declined an offer of help and blew himself up, a neighbor said.
Personnel from the Orange County Sheriff's Bomb Squad and Orange County Fire Authority Hazardous Materials Unit were combing through the home Monday morning after finding a second explosive that they planned to detonate.
Authorities said they would continue to look for additional explosives before rendering the home safe and allowing residents back into the neighborhood.
Laurie Raphoon, a neighbor, was one of the residents who was evacuated.

She said she was shocked when she heard an explosion. She said it happened after a neighbor, who she described as in his late 40s or early 50s, collapsed outside his home and refused to be taken to a hospital.
"Neighbors were trying to convince him to go to the hospital," Raphoon said. "An hour or two later we heard an explosion."
