People gathered in Woodburn Saturday night for a candlelight vigil in honor of those killed and hurt in a bomb explosion at a bank Friday.

PORTLAND, Ore. (AP) — The investigation into a bomb blast at a bank that killed two police officers and left a third in critical condition continued Sunday with no indication of a motive.

The bomb exploded late Friday afternoon at a West Coast Bank branch office in Woodburn, a city of nearly 23,000 in the Willamette Valley farmland just south of Portland.

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

Lt. Sheila Lorance of the Marion County sheriff's office, the lead agency in the case, said investigators "are being meticulous, and they are being extremely thorough" as they search for clues.

But Lorance had no details she could add, including any answers to the question about why the officers took the bomb into the bank after it was found outside.

"There has been a lot of speculation about that but that has yet to be determined," said Lt. Gregg Hastings, spokesman for the Oregon State Police, which is assisting in the investigation along with the FBI and the federal Bureau of Alcohol, Tobacco, Firearms and Explosives.

A West Coast Bank branch manager found the device Friday after checking the bank grounds following a call about a bomb threat to a nearby Wells Fargo bank branch that turned up a device that was harmless.

A $35,000 reward has been offered for any tips in the bombing, and police were asking the public for help.

"That person is very dangerous and that person needs to be found as soon as possible," Hastings said.

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 on Monday.

He expressed sympathy for the families and urged the public to offer any tips.

Sznewajs also said all records and money kept at the branch were secure, and it would reopen as soon as possible.
