On June 23, Sermano was found guilty by a jury of second degree murder and aggravated assault.
On June 26, 2007, he was in San Juan Capistrano Park with two acquaintances, Gutierrez, 39, and Maurico Molina, 34.
Prosecutors said he got into an argument with Gutierrez over who was a better singer. They said Molina tried to break up the fight and stabbed Gutierrez twice.
Sermano also took out a knife and accidentally stabbed Molina. Authorities said Sermano then stabbed Gutierrez repeatedly.
Both Molina and Gutierrez were rushed to the hospital where Gutierrez died and Molina was treated for a stab wound.
In September of 2009, Molina pleaded guilty to voluntary manslaughter. He was sentenced in May to 11 years in state prison. He also testified at Sermano's trial.
