The property-management executive who slayed his wife and daughter in a double murder-suicide over the weekend was facing allegations that he had stolen $22,000 from a client.

Gabriel Management CEO Steven Dym was in state Supreme Court last week on allegations he took $22,000 from a client’s account and refused to turn over his books after he was caught, the New York Post reported.

“We don’t know what happened to the books,” said Richard Walsh, the lawyer trying to find any monies Dym had taken. “We don’t know how much money is missing and we were in active discovery.”

Dym, 52, killed his teenage daughter and wife with a 12-guage shotgun in their Westchester home and then fatally shot himself.

Walsh said Dym came up with several excuses why he couldn’t produce about six boxes of financial records.

But this wasn’t the first time he was accused of stealing from clients. He had been tampering with funds about five years ago from a co-op in Soho, one of the owners claims.

“There were a number of buildings he ripped off,” said Louis K. Maisel, who owns a co-op at 141 Prince Street. “Our case attorney negotiated a settlement of $50,000.” [NYP] – Rich Bockmann
