Well, I'm glad to see that they have arrested at least one suspect in the case, although they are not yet going on record as to any motive nor are they speculating publicly about possible accomplices.

Salem is just a few miles down from Woodburn; I've forgotten how many but somewhere between 10 and 20, I'd say.

Earlier they said that some of the parts for the bomb were bought in Bend. Bend, the biggest town in Central Oregon, is on the other side of the Cascade Range, a goodly distance from Woodburn.
