UPDATE: DNA evidence connects homeless man to Fred Meyer explosion; charges dropped against previous suspect

A 26-year-old homeless man is facing three felony charges in connection with a small explosion in a Southeast Portland Fred Meyer store.

Joshua Hines is facing a first-degree arson charge and unlawful manufacturing and possession of a destructive device charges, court records show. He was arrested late Friday night and booked into the Multnomah County Inverness Jail early the next morning, records show.

Police said tips to Crime Stoppers and information learned from social media were key in identifying and arresting him. They're now asking the public to help identify a potential victim who is shown in a surveillance image.

The man shown in the surveillance image may be an attempted assault victim, Sgt. Pete Simpson, a Portland police spokesman, said in an email.

"Reckless behavior that leads to a person injured can be considered an assault," Simpson said.

There are no known injuries in the blast, he said, and the store didn't sustain any major damage.

Portland police are asking the public to help identify a potential victim of an explosion at the Foster Fred Meyer on May 21, 2016.

Authorities responded to the Foster Fred Meyer, 5253 S.E. 82nd Ave., just before noon on May 21 on the report of a small explosion in one of the store's aisles, Portland police said in a news release.

Police said a small explosive device -- which court records describe as a bomb -- caused the blast. The explosion happened in an aisle where small, travel-size items are displayed.

Hines was arraigned Monday and is being held on $260,000 bail, records show. He's next scheduled to appear in court Tuesday.

Crime Stoppers of Oregon released on June 1 a surveillance image of the man suspected in the case, police said. They ask anyone who has information about who the potential victim is to contact Investigator Rick McGraw at 503-823-3797 or rick.mcgraw@portlandoregon.gov or Detective Joe Luiz at 503-823-3408 or joseph.luiz@portlandoregon.gov.
