SALEM (AP) - Authorities have identified the man arrested in the bombing of an Oregon bank and say he is accused of murder.

The Marion County district attorney's office said Monday the suspect is 32-year-old Joshua A. Turnidge.

Authorities say he is the man shown in surveillance photographs released Sunday.

Two law enforcement officers died in the blast Friday evening, and one was critically injured.

Authorities announced the arrest late Sunday.

They initially declined to release the suspect's name, saying it would jeopardize the integrity of the investigation and the safety of officers still working to see if others were involved. "We do believe the person responsible for the bombing is in custody,'' Deputy District Attorney Courtland Geyer said late Sunday.

Turnidge was arrested in Salem, just south of Woodburn, where Friday's bombing occurred.

Officers made the arrest shortly after Sheriff Russ Isham of Marion County released surveillance photos of a "person of interest." Geyer would not say if a tip led to the arrest.

"I'm really proud of those who tirelessly worked to get us to this point and am humbled by the community's support,'' Isham said. "We know there is still a lot of hard work ahead of us, but this development will help bring relief to the local community and the officer's families.''

Earlier Sunday, Isham said cell phones and items that might have been used to make the Woodburn bomb were bought in the central Oregon city of Bend last month. Authorities would not elaborate on how cell phones might have been used. Bombers often use cell phone signals to remotely detonate explosives.

Geyer said revealing anything about the "manner and build'' of the bomb would hurt the investigation.

The manager of a Woodburn branch of West Coast Bank found the device Friday after a call about a bomb threat to a nearby Wells Fargo bank branch that turned up a harmless device. The bomb was found outside, but the officers took the bomb into the bank, where it exploded.

Woodburn Police Chief Scott Russell remained in critical condition Sunday at a Portland hospital as a result of the blast that killed Woodburn police Capt. Tom Tennant and Oregon State Police Senior Trooper William Hakim.

Robert Sznewajs, the CEO of West Coast Bank, said Sunday that the bank planned to establish a fund for the families of the law enforcement officers.
