A neighborhood in southern California 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 in Costa Mesa.
Someone noticed a man on the ground in a front yard and called an ambulance.
The man declined an offer of help. It wasn't until later, police and neighbors said, that he blew himself up.
"He was under his own power to get back to his own residence," said Sgt. Jerry Hildeman, of the Costa Mesa Police Department. "We believed we didn’t have any reason to go further."
The police came back and found the man dead. They believe he was wearing two pipebombs. They say it's unclear whether he committed suicide or accidentially killed himself.
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 detonated.
FBI agents assisted local authorities in case there were any federal laws broken, said Laura Eimiller, an FBI spokeswoman.
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."
