A federal jury in Hartford has found a New York man guilty of using counterfeit $100 bills to purchase electronic equipment at the Target in Waterford and four other retail stores, U.S. Attorney David B. Fein announced Thursday.

Shaun Whitehead, 26, of Brooklyn, N.Y., was found guilty Wednesday of five counts of passing counterfeit currency by a jury that had deliberated for one hour following a three-day trial, according to a spokesman at the U.S. Attorney's Office.

Early in 2011, Whitehead had used the bogus bills to purchase iPads and Bose headsets from stores in Windsor, Waterford, Lisbon, South Windsor and Naugatuck, authorities said. He faces a maximum of 20 years in prison and a fine of up to $250,000 on each count. A sentencing date has not been scheduled.

Whitehead has been detained since March 9, 2011, when he was arrested in Massachusetts on a state larceny charge. He has been in federal custody since Aug. 24, 2012.

The case was investigated by the U.S. Secret Service, with assistance from Connecticut state police and police departments in Windsor, Waterford, South Windsor, Naugatuck and North Attleborough, Mass.
