He faces up to life in prison when he is sentenced Feb. 4 by 3rd District Judge Elizabeth Hruby-Mills.
Alverez and Veracruz were part of a group hanging out and drinking in Riverside Park, 700 North and 1400 West in Salt Lake City, on the evening of May 5, 2011.
The two men began arguing, and soon there was talk of fighting. When Veracruz walked away, Alverez fired three shots from a semiautomatic handgun, prosecutors say.
Veracruz was hit in the back of the right arm. A second round went into the right side of his back. A third shot hit the left side of his back, piercing his spleen, stomach and aorta before stopping in his lung.
Defense attorneys have said Alverez was protecting himself from a perceived threat and believed Veracruz was going to rob him and fired only when he saw the victim reaching for something in a bag.
A mistrial was declared in October after a witness offered testimony that defense attorneys said tainted the jury.
Alverez was convicted of homicide in 1980 for running over 59-year-old David Bingham with a truck in Ogden the previous year. Alverez was paroled in 1985 but has spent time in state and federal prison since then for various crimes.
