BANGOR, Maine — Detective Erik Tall tried to check the recently updated address of a local lifetime registrant on the Maine Sex Offender Registry, and after failing on several occasions finally caught up with the man and arrested him, Bangor police Sgt. Paul Edwards said.

Joshua D. Keen, 30, was convicted of gross sexual assault in December 2001 in Machias Superior Court and now must register as a sex offender on the Maine Sex Offender Registry.

Keen updated his address in April saying he was living on Willow Street, but each time Tall tried to verify his address, he was nowhere to be found, Edwards said.

After checking and checking, the Bangor detective finally caught up with Keen on May 2 and arrested him for felony failure to register or update the sex offender registry, the sergeant said. The charge was upgraded to a Class B felony because Keen has two prior convictions for failing to comply with the sex offender registry act, Edwards said. He faces a penalty of up to 10 years in prison, if convicted.

Keen, who lists his mailing address as the Hope House, a Bangor shelter for people struggling with drugs and alcohol, was taken to Penobscot County Jail after his arrest last week. He has since been released, a jail official said. (Nok-Noi Ricker, BDN)
