PHOENIX - UPDATE: The jury on Tuesday found Richard Chrisman guilty of aggravated assault . They were unable to come to a decision on two other counts.
Jurors in the trial of an ex-Phoenix police officer charged with fatally shooting an unarmed suspect and his dog reached a verdict in the case after about four days of deliberations.
Maricopa County Superior Court officials said the jury failed to reach verdicts on two of the three counts against Richard Chrisman late Monday, but the court did not specify which ones.
The verdict will be read Tuesday morning.
Chrisman has pleaded not guilty to second-degree murder, aggravated assault and animal cruelty. He maintains the October 2010 shootings of Daniel Rodriguez, 29, and his pit bull were in self-defense.
The former officer testified how pepper spray and his stun gun failed to stop the suspect's aggressive behavior as the two then struggled, and Rodriguez picked up a bicycle from the living room floor.
"He was going to smash my brains in. ... I fired two rounds, center mass," Chrisman told jurors during his trial.
Rodriguez died at the scene.
Prosecutor Juan Martinez told jurors Chrisman arrived at Rodriguez's home as the aggressor, barged in and pressed a gun to his head before the fatal shooting.
Martinez said the evidence doesn't show Rodriguez was assaulting the officer. He said Chrisman shot Rodriguez's "friendly" dog after the animal wagged his tail at him, and that the officer failed to even try to talk to Rodriguez.
"A person cannot take out a gun, point it at someone and then when that person steps back, shoot them," Martinez told jurors in closing arguments.
Defense attorney Craig Mehrens urged jurors not to believe Martinez's "tale."
He said it's hard to believe that a nine-year veteran of the force who had never fired his gun would have decided "today's the day" to kill someone and chose Rodriguez as his victim.
Chrisman testified that he and another officer arrived at the scene and made contact with the woman who had called authorities to report that her son, Rodriguez, had become violent. Chrisman said she was frightened and excited.
"She was crying, shaking," Chrisman testified. "She told us that her son, Danny, goes out, he leaves the house for several days at a time. When he comes home, he gets real violent and angry and starts destroying stuff and hurts her."
Authorities say Chrisman used unnecessary excessive force after Rodriguez questioned the right of the two officers to be inside his trailer.
The other officer on the scene with Chrisman told investigators the dog wasn't attacking either of them, and that the man wasn't a threat when Chrisman shot him. Chrisman says the officer wasn't doing his job, and was outside the trailer when the shooting occurred.
Chrisman was fired from the department about five months after the shooting. Opening statements in his trial began in early August.
