Los Angeles man arrested in connection to deadly Northern California fireworks explosion

Garfield High School in East Los Angeles was evacuated on Monday morning as investigators served a search warrant at a nearby home connected to a deadly explosion in Northern California. 

Cal Fire, which led the investigation into the deadly explosion, said its personnel discovered several items, including explosives, at the home that required help from the Los Angeles County Sheriff's Department bomb squad. 

They evacuated Garfield High School as a precaution. Dr. Carlos Montes, Region East Director for James A. Garfield High School, said all students and staff were being temporarily relocated to Griffith STEAM Magnet Middle School. Staff were allowed to return to the campus several hours later. 

Deputies removed several boxes from the home. The Bureau of Alcohol, Tobacco, Firearms and Explosives, which has been aiding Cal Fire in its investigation, was also at the scene. Cal Fire said authorities arrested one person for allegedly possessing explosives and destructive devices. 

Public records showed that Luis Refugio Acosta owns the property. Cal Fire could not confirm that they took Refgio Acosta into custody; however, LA County jail records showed a man named Luis R. Acosta was booked this morning for a destructive device near certain places. 

The explosion happened on July 1 at a fireworks facility in Esparto, roughly 35 miles northwest of Sacramento, and killed seven people. It forced the evacuation of nearby residents and cut power to about 2,200 households, some of whom are still repairing damage from the explosion.
