A 46-year-old man was justified in killing a home intruder who investigators say broke into his Southeast Portland house last year to rob him, a grand jury found.

The grand jury last week determined that Robert Chambers was acting in self-defense on July 14 when he shot Anthony James Lazarides, 30, sometime before 1 a.m.

But the grand jury indicted Chambers for another crime -- being a felon in possession of a firearm. Chambers was convicted of first-degree theft in 2013.

Deputy District Attorney Steve O'Hagan said he couldn't release details of the shooting because his office has a pending criminal case against Chambers for the gun possession charge.

Homicide detectives with the Portland Police Bureau didn't return calls this week seeking details about the circumstances leading up to the killing of Lazarides.

Police previously said that Lazarides was with at least one other person who broke into the home in the 8300 block of Southeast 64th Avenue. When Chambers shot Lazarides, the accomplice or accomplices fled, police said.

Chambers was wounded. It's unclear if Lazarides knew Chambers.

In 2006, Chambers was the victim of another home invasion -- that time by a man who was angry at him for a failed business transaction over the purchase of an ice cream truck. The intruder, who killed one of Chambers' employees, held Chambers captive at gunpoint in his home for two hours before Chambers was able to escape.

Lazarides had an extensive criminal history. Since he turned 18, he had been convicted of assault, reckless driving and possession or delivery of marijuana, cocaine, methamphetamine and heroin.

Chambers' killing of Lazarides was the third such incident of a resident shooting an intruder in Portland last summer, police say.

On the afternoon of June 22, 78-year-old Robert McCall shot Stanley Wilson II in the abdomen as the ex-NFL football player allegedly tried to break into McCall's house in the 4900 block of Southwest Humphrey Boulevard. A grand jury cleared McCall of any criminal wrongdoing.

On June 26, David Daniel McCrary was fatally shot in the back of the head by a woman in her Southeast Portland home near Southeast 122nd Avenue and Holgate Street. Police said Tara-Alexis Ford, 33, killed McCrary after the family arrived home and discovered him in the bedroom of her 10-year-old daughter. A grand jury cleared Ford of any wrongdoing.
