Ruiz was a veteran of World War I, and got hooked on barbiturates after the war. He had a deadly aim afterwards, and was recruited by Don Rico Granados as a Capo in charge of the Ruiz Crew. By the time that he was in the field of the Granados War, his two men had been killed.
Ruiz and Paul Morales attacked Basso Oil Fill & Co, but Morales was shanked and died. Shortly after, Jimmy Lira cut down a fence with a cutter and Dominic moved through and beat Ruiz with a bat. When Ruiz fell to his knees, he put the bat in his mouth and slammed his head to the pavement, crushing his head in.
