An Oregon jury will begin hearing arguments Thursday before deciding whether a father and son should be sentenced to death for planting a bomb that killed two police officers inside a bank.

It took the same jurors less than five hours on Wednesday to find 58-year-old Bruce Turnidge and 34-year-old Joshua Turnidge guilty of aggravated murder and other charges.

Prosecutors say the men planted a bomb at a bank in Woodburn two years ago this week. The device went off as state police bomb technician William Hakim tried to dismantle it, killing him and Woodburn police Capt. Tom Tennant.

The town's police chief, Scott Russell, lost a leg in the explosion.

The father and son turned against each other during the trial.
