After a nearly two-week trial, a jury found David Jesus Barron, 26, guilty in the July 28 fatal shooting of Miguel Leon-Fregoso, 27.
Barron was also convicted of attempted murder for firing two shots at Leon's friend before speeding off in his truck.
He faces a maximum of 79 years to life in prison when he is sentenced July 20 by Superior Court Judge Bernard Revak.
Prosecutor Greg Walden said Leon was at a bar celebrating the birthday of a woman he had been dating when the woman -- who had also been having sex with Barron -- told the artist that Barron had criticized his artwork.
He said Leon went across the street to another bar to confront Barron about the comments, and afterwards, Barron found Leon in an alley and shot him in the face with a .357 magnum, then fired at Leon's friend.
Barron's attorney, Alan Spears, told the jury his client shot Leon because he thought the artist was going to shoot him.
Spears said the case was about "betrayal, disrespect and the consequences of that disrespect."
He said Barron met the woman at the bar before Leon arrived, but left to avoid any problems.
However, Leon and his friends confronted him at the other bar, and Barron left the bar in his pickup truck, but was again confronted by Leon and a friend, the defense attorney said.
As Barron pulled up in the alley, he saw Leon's friend with a gun and knocked it out of his hand by opening the door to his truck, Spears said.
He said Barron thought Leon was also going to pull a gun, and shot him "out of fear."
