Garcia is accused of setting fire to several piles of laundry on July 24 in the Stanton residence he shares with his sister, according to the Orange County District Attorney's Office. The fire did not spread throughout the house.
The OCDA alleges Garcia poisoned his dog after the fires went out. Garcia allegedly fed his 7-year-old dachshund mix a variety of pills. He then allegedly took a large kitchen knife and slit the dog's throat, according to the district attorney's office. The dog died on the suspect's bed.
Garcia's sister came home and called 911. Orange County Sheriff's deputies and Orange County Fire Authority personnel responded to the scene.
The suspect was hospitalized with self-inflicted injuries and arrested.
Garcia is scheduled for arraignment Wednesday in Westminster. The OCDA said in a statement $250,000 bail will be requested.
Garcia faces a maximum of eight years and four months in state prison.
