Agents from the federal Bureau of Alcohol, Tobacco, Firearms and Explosives are investigating the theft of more than 30 guns, mostly rifles, from a trailer stolen from the lot of Oxford Suites hotel on Hayden Island Monday morning.

The federal Bureau of Alcohol, Tobacco, Firearms and Explosives and the National Shooting Sports Foundation, a firearms industry trade association, said Friday they’ve pooled resources to offer a reward of up to $10,000 for information leading to the arrest of those responsible for the theft of 34 guns from a federal gun licensee in Portland.
