On Friday, a judge determined that there was probable cause to show that the boy fatally shot his father, Vincent Romero, 29, and Timothy Romans, 39, of San Carlos with a .22-caliber rifle. The boy faces two counts of premeditated murder.
The boy was charged as a juvenile, but authorities are pushing to have him tried as an adult, however unlikely that is, Melnick said. If convicted as a minor, the boy could be sent to juvenile detention until he turns 18.
Police had responded to calls of domestic violence at the Romero home in the past, but authorities were searching records Saturday to determine when those calls were placed, Melnick said.
"We're going to use every avenue of the law that's available to us, but we're also looking at the human side," he said.
Melnick said officers arrived at Romero's home within minutes of the shooting Wednesday. They found one victim just outside the front door and the other dead in an upstairs room.
