The victim, Steven Arredondo of Rancho Cucamonga, was found in the parking lot of the Montecito Apartments in the 11300 block of Mountain View Drive last Thursday.
On Saturday, authorities arrested 25-year-old Kevin Taylor and three male juveniles in connection with the murder. Officials say Arredondo was shot during an altercation involving the four suspects.
Taylor was taken to West Valley Detention Center and booked for murder. The juveniles were taken to San Bernardino County Juvenile Hall and are also being held for murder.
