There were also numerous rounds for each weapon and spare magazines for both rifles, loaded with live rounds, at the home of Luis Placido, 31, in the 11200 block of Grape Street, said sheriff’s Lt. Richard Westin of the department’s Operations Safe Streets Bureau.

With the permission of Placido’s parole agent, detectives drove to his home Thursday night to find the cache. Placido, an admitted member of a local street gang, is on parole for allegedly assaulting a police officer with a firearm.

He was reportedly confined to his home and ordered to wear a GPS sensor to his ankle, Westin said.

Placido was arrested and booked at the sheriff’s Century Regional Detention Facility where he was being held without bail, due to his parole status.

Westin said the investigation into the origin of the weapons and how Placido came to possess them was ongoing.
