A 45-year-old man who shot a man in the stomach and another in the back at a Mililani park on July 4, 2011, then fired more shots at the wounded men while they were on the ground, was found guilty Tuesday of assault and reckless endangering.

State jurors returned the verdicts in the attempted-murder trial of Richard P. Silva III.

"I think they were sympathetic towards the defendant," said Deputy Prosecutor Rodney Veary.

The maximum penalties are five years in prison for the assault and one year in jail for the reckless endangering.

Silva, however, is facing a mandatory 20-year prison term when he is sentenced in March because the jury also found him guilty of using a firearm to commit the assault. The jurors found him not guilty of carrying a firearm without a permit and of being a felon in possession of a firearm.

"Clearly, from the communication, the jury had reasonable doubt as to who brought the gun," said Silva’s lawyer, state Public Defender Jack Tonaki.

During their deliberations Monday, the jurors asked the court whether it were possible for them to return unanimous verdicts if they could not agree on who brought the weapon.

Silva testified last week that he shot Chadwick Ceno and Travis Joaquin in self-defense at Kipapa Park. He said he shot Ceno in the stomach during a struggle after Ceno approached him with a gun and pointed it at his face. After gaining control of the weapon, Silva testified, he fired the gun randomly in the dark because he was afraid others were after him.

Ceno and Joaquin said they went to the park unarmed.

Veary said that after Silva shot Ceno in the stomach and Joaquin in the back, Silva went back to Ceno, fired more shots at him and then walked over to Joaquin and did the same.

Joaquin suffered two more gunshot wounds, one to his right arm and the other to his right side. Ceno escaped additional injury.

A third man who was at the park, William Peters, said he went there with Ceno to break up any fight after Silva had called out David Kahanu, a friend of the victims. Veary said Joaquin went there to see what was going on.

Silva testified he went to the park not for a fight, but to talk to Kahanu to settle a dispute between them.
