Boxing trainer convicted of murder for opening fire at Vista club, killing fellow trainer

Posted: Updated:

SAN DIEGO (CNS) - A trainer who opened fire at a Vista boxing club after being barred from the gym, killing another trainer and wounding two other people, was convicted Wednesday of first-degree murder and other charges.

After a day and a half of deliberations, a jury also found 50-year-old Mark Anthony Diaz guilty of attempted murder, assault with a semiautomatic firearm and making a threat.

Diaz wept openly as a clerk read the verdict in the courtroom of Judge Kerry Wells.

The defendant faces more than 96 years to life in prison, with sentencing set for June 3.

Boxer Ricardo "Ricky" Gutierrez, 21, and trainer Peter Moreno were wounded during the April 7, 2010, shooting at Pacific Coast Gym that killed 52-year-old Hector Gil.

Albert Gamez, a "cut man" who knew both the defendant and the victim, testified that Diaz called him last February and asked him not to help Gutierrez with an upcoming fight because Diaz and Gutierrez had had a disagreement. Gutierrez had decided to train with Hector Gil, Gamez testified.

The witness said Gil told him that Diaz had been threatening him.

At another fighter's bout in April 2010, Gil had Gamez listen to voice mail messages from Diaz, the witness testified.

Gamez said Diaz left a message saying he was "going to blast him or shoot him."

"He (the defendant) said, `I'm going to blast you, I'm going to shoot you. You're gonna die," Gamez testified. "He (Gil) was clearly bothered by it."

Gamez said he tried to contact Diaz to explain why he was helping Gutierrez, but the calls were never returned.

The witness said Diaz left another message for Gil that said, "You're (expletive) with the wrong person. You watch. You watch. You're gonna get yours."

Salvador Gonzalez, who took his son to train at Pacific Coast Gym, said he and Gil became close, and the victim confided in him about a month before the shooting that Diaz had threatened to hurt him because he had taken his fighter.
