Deputies announced Monday they had identified three 15-year-old boys as suspects. Each admitted to taking part in the incidents, according to Deputy Bryon O'Neil of the Clackamas County Sheriff's Office.

There were no reports of injuries related to the bottle bombs, but there was some property damage. The investigation was ongoing.

If the total damage estimate is more than $1,000 the suspects could face up to five years in jail and a $10,000 fine, O'Neil said.
