YAKIMA, Wash. — Yakima County prosecutors have filed a gun charge against convicted murderer Dale Barr, who has been repeatedly arrested since his 2007 release from prison for a gang shooting in Yakima almost 18 years ago.

According to court records, Yakima patrol officers were investigating a domestic disturbance Feb. 6 in the 1200 block of South Seventh Street when they spotted a man later identified as Barr coming out of an alley near Seventh and Spruce streets.

Because Barr matched the description of one of two suspects in the disturbance, and because the disturbance involved a pistol, the officers began searching the area for a weapon.

After backtracking on Barr’s route through the alley, officers said they found a loaded .38-caliber Smith & Wesson revolver hidden under a pile of leaves.

After police said a witness confirmed Barr had been at the disturbance, he was arrested on a gun charge. He also had a warrant for driving under the influence.

On Tuesday prosecutors filed a charge of first-degree unlawful possession of a firearm against him. He remains in custody on $150,000 bail.

Barr was 15 years old on the night of July 16, 1995, when he opened fire on a group of rival gang members walking along the street near the intersection of Sixth Avenue and Nob Hill Boulevard in Yakima.

One youth, 15-year-old Andy Garcia, died almost instantly from a bullet wound to the heart. Another teenager was shot in the chest but survived.

Barr was originally sentenced to 18 years in prison. His conviction was eventually vacated by the state Supreme Court on appeal as part of a 2002 ruling, known as the Andress decision, that invalidated dozens of felony murder convictions statewide.

Prosecutors refiled charges against Barr, but his sentence was reduced to 12 years on the second go-round.

Since his release, the now 32-year-old Barr has been arrested several times, according to court records. In 2011, he was sentenced to 20 months in prison for his role in a gang-related drive-by shooting near Fifth and Cherry avenues.
