VALLEJO, Calif. (KGO) -- A domestic dispute turned deadly in Vallejo Thursday morning. The victim was a veteran Richmond police officer and the man accused of shooting him is the father of the victim's own grandchild.Off-duty police officer Augustine "Gus" Vegas was killed early Thursday morning at his Vallejo home. He had been with the Richmond Police Department for 15 years and was well known in his community.Police arrested the suspect, Robert Vega,30, a short time later in Fairfield.The shooting happened in the quiet Vallejo neighborhood where neighbors knew 58-year-old Vegas as a friendly and devoted family man.It was a somber procession to end a devastating day for the Richmond Police Department after one of their own was killed."The suspect was the father of Gus' 6-year-old grandson," said Vallejo police Lt. Jeff Bassett at a news conference.It happened just after 4:30 a.m. in Vallejo's Glen Cove neighborhood. It was a domestic incident involving Vegas' grown daughter, a young grandson, and the boy's father, suspect Robert Vega."There were other family members that were present and witnessed the shooting," Bassett said.Richmond police Capt. Mark Gagan knew Vegas well."Probably trying to stabilize the situation. Probably trying to be a mediator, and a protector for his daughter and just end the situation peacefully," Gagan said.The boy and the suspect were located a short time later in Fairfield, where late Thursday police could be seen from Sky7 HD going in and out with what appeared to be evidence bags.The 30-year-old Vega was a 2011 graduate of the Napa Valley Police Academy, the same academy Vegas graduated from in 1990.Vegas' wife Sandra was also injured during the incident, reportedly after jumping from an upstairs window.Vegas was also active in foster care, the community and was a devoted family man, with more than two dozen children and grandchildren."Gus was very likeable, always pleasant, always in a good mood," said Richmond Police Chief Owen Brown. "Just really related to people in a natural way. I never saw him have a bad day or be in a bad mood. And we are stunned, we are stunned. We are saddened."
