Police made an arrest Wednesday in Sunday’s triple slaying and were also investigating whether the suspect was involved in another shooting earlier Sunday.
Police said suspected gang member Edwin Ramos, 21, was arrested after a search warrant was served at an El Sobrante residence. They said the warrant resulted from a combination of police leads and tips.
Police also impounded a Chrysler 300 that they say was involved in the shooting.
Tony Bologna, 48, and two of his sons, Michael, 20, and Matthew, 16, were driving home Sunday from a family gathering in Fairfield when they were shot just blocks from their home in the Excelsior district.
Investigators do not believe the killings stemmed from a road-rage incident, according to Lt. Mike Stasko, who heads the San Francisco police homicide unit.
“There wasn’t enough time for this to develop into a road-rage incident,” he said.
Tony Bologna and his sons had been at a barbecue at the house of Lorraine Kennedy, his sister. He left the gathering with his sons so he could prepare for his job at Draeger’s Market in San Mateo, where he worked as a night shift manager, family members said.
The Chrysler’s driver stared down Tony Bologna, who then backed up for the suspect vehicle. Instead of moving along, police say, someone opened fire, hitting all three victims.
Tony Bologna, an Excelsior district native, had a wife, daughter and a third son.
“This is senseless,” Kennedy said. “We had a real family, a real family. They took our family away.”
Police said the killings were “random” in that the victims did not know anyone in the Chrysler.
Homicide Inspector Brian Delahunty said the Police Department is still pursuing a lead that indicates the suspect was involved in another shooting earlier Sunday. The Chrysler matches the description of a vehicle used in an earlier shooting on Cesar Chavez Avenue, Stasko said.
Ramos, who is being held on three counts of homicide, remains in custody. He has not yet been charged in the slayings.
The killings moved San Francisco’s homicide total to 51 for 2008. In 2007, The City saw a decade-high 98 homicides.
