The father of a Vallejo teen allegedly shot a 17-year-old Richmond boy to death early Sunday after the two youths had fought at a party, police said.

Lt. Sid DeJesus said that Randee Damar Williams Sr., 44, of Vallejo, was arrested on suspicion of killing the Richmond teen at about 3:35 a.m. in the 300 block of Robles Way.

DeJesus said that a 19-year-old Vallejo teen was in the fight with the Richmond youth as the party was winding down. The older youth called his father, Williams, to the home, DeJesus added.

It was not immediately clear if the 19-year-old was injured in the fight.

Police received multiple 9-1-1 calls, reporting that they heard a vehicle approaching the area, about six gunshots, and then screams. Upon arrival, police found the teenager's body on the ground outside the home with gunshot wounds in his body and head. He was pronounced dead at the scene.

Police have not released his name.

Officers also found about five .40-caliber shell casings at the scene.

Witnesses, including the victim's girlfriend, were taken to police headquarters for questioning.

After further investigation, police identified the suspect and converged at his home in the 1000 block of Thelma Avenue at approximately 10 a.m., DeJesus said.

Williams was arrested without incident, DeJesus added.

He will be booked into Solano County jail, and the case remains under investigation.

This latest homicide was the 21st in Vallejo this year.
