The deadly incident unfolded last month when the suspect's mother called 911 and mentioned her son, Joshua Bonilla, had schizophrenia.
Officers arrived at the home on Valerio Street and spoke with Bonilla's brother. They then went inside the home where they found Bonilla stabbing his father, Elias, with a pair of scissors.
Police say when he refused officer commands, they shot him.
