Timothy Wanamaker, the city’s one-time deputy director of general services, resigned Friday after alerting city officials to his legal woes in Buffalo, N.Y.

Wanamaker, who came to Alexandria after a short stint as a California city manager, told supervisors last week he had pleaded guilty to a felony charge of stealing government funds from the city of Buffalo between 2004 and 2008 while serving in a variety of top posts. He was immediately put on paid administrative leave, said Tony Castrilli, city spokesman.

Wanamaker tendered his resignation about 48 hours after revealing he had stolen roughly $30,000 in municipal and federal funds, spending much of it on travel, entertainment, car rentals and hotel rooms.

Internal auditors are reviewing Wanamaker’s financial transactions in the wake of his plea deal with federal prosecutors. The report is expected to take several weeks to finish, Castrilli said.
