The six suspects accused of brutally beating and robbing an elderly Harrison couple last September appeared in court Tuesday and were charged with burglary.

Throughout the proceedings, the six men, including the alleged mastermind of the home invasion, Gary Pilavdjian, remained silent.

Pilavdjian, of New Rochelle, was a contractor for Frieda and William Schwartz for nearly two years prior to the incident. The Schwartzes say they even trusted him enough to leave him alone in their home.

?You can't trust nobody anymore, doesn't matter how close or how friendly he is,? William Schwartz says.

Police say Pilavdjian teamed up with John Mandracchia, of New Rochelle, and hired four men to follow the couple from their jewelry store in the Bronx and attack them at their home. The men allegedly stole money, jewelry and a Mercedes Benz.

Following a four-month investigation, police arrested the suspects as they allegedly attempted to sell the stolen jewelry at pawn shops around the country.

According to the district attorney, Pilavdjian may be facing additional charges for three similar violent home invasions in Westchester. Pilavdjian and his alleged accomplices are due back in court in two weeks.
