A Marine colonel convicted of sexually abusing a child will be stripped of his retirement benefits and have to register as a sex offender when he gets out of prison, a Corps official said.

Col. Daniel H. Wilson was sentenced on Sunday to spend nearly five years in prison and to be dismissed from the Marine Corps. Wilson, 56, had been the operations officer for II Marine Expeditionary Force.

Being dismissed from the service is the equivalent of a dishonorable discharge, which means Wilson will automatically forfeit his pay, allowances and other entitlements, said II MEF spokesman Lt. Col. Michael Armistead.
