Ramos, an alleged gang member, was accused of shooting Bologna, 48, and his sons Michael, 20, and Matthew, 16, after mistaking them for rival gang members in the Excelsior District of San Francisco on June 22, 2008.
Bologna's teenage son Andrew was also on the car that day. He was not injured and testified as the prosecution's star witness. He identified Ramos as the shooter.
Ramos claims another gang member in his car fired the gun and that he never knew there would be a shooting.
There were audible gasps and crying in the courtroom as the guilty verdicts were read Wednesday afternoon.
"This justice today does not bring my family back, but it helps a little," Anthony Bologna's sister Lorraine Kennedy said.
After the verdict was announced, Ramos' attorney Marla Zamora release a statement saying, "We are surprised that the jury could not agree on whether Mr. Ramos actually fired the gun, yet still chose to convict on first degree murder. Justice has not been delivered to the City of San Francisco nor the victims so long as the killer, Wilfredo Reyes, is still on the streets."
Ramos was also found guilty of one count of attempted murder.
