Ricardo Arturo Zapata, 31, was one of two men found shot to death inside a converted garage apartment on June Street in the Muscoy neighborhood of San Bernardino. Zapata and 39-year-old Michael Ricardo Vargas were discovered after neighbors reported hearing gunshots; both suffered fatal gunshot wounds and their deaths were classified as a double homicide.

Investigators arrested 28-year-old Roberto Estrada Lopez, a Muscoy resident who was living in a motorhome parked nearby. Lopez was charged with two counts of murder, two counts of discharging a firearm causing great bodily injury or death, and kidnapping, and he pleaded not guilty at his initial court appearance. Officials have not released a motive or specific details explaining what led to the shootings.

Anyone who knew Ricardo Arturo Zapata, his movements in early February 2017, or who has information about activity around the June Street apartment is asked to come forward.
