More than 1,200 guns and an estimated two tons of ammunition were discovered at the upscale Southern California home of a man who was found dead inside an SUV last week, according to police.

Officers received a report around 5 p.m. Friday about the discovery of the body in the 1700 block of Palisades Drive in Pacific Palisades, Los Angeles Police Department officials said.

After learning that the man lived on the same street, detectives with the LAPD's elite Robbery-Homicide Division served a search warrant at the home and found a arsenal of handguns, shotguns, rifles and ammunition, police said.

A bomb squad searched the home for explosives and gave investigators the all-clear to seize the weapons.

"The boxes of ammunition were out behind the garage and they were just lots of them, piled at least 8-feet tall, and the pile just kept getting bigger and bigger and bigger," said a neighbor, who did not want to be identified.

Police were trying to determine the origin of the guns and whether they were legally being kept at the home.

The neighbor said the man claimed to be affiliated with the CIA and the military.

The man's identity has not been released.
