ATF's three year investigation, assisted by the Bedford (Ohio) Police Department, culminated in the arrest of Mourad Topalian, a college vice president and chairman of the Armenian National Committee of America. Topalian, linked to the overall contents of the storage unit, pled guilty to possession of stolen explosives and possession of automatic firearms. At sentencing, he was given an upward enhancement for knowing the stolen explosives would be used in a bombing.
