The ATM card of slain Jersey City Heights resident Hossam Armanious was used several times in the week after his death to withdraw thousands of dollars from his bank account, Hudson County Prosecutor Edward DeFazio said yesterday. The withdrawals, made on several occasions from banks in the Jersey City Heights and in mid-town Manhattan, continued for up to a week after the bodies of Armanious, his wife, Amal Garas, and their daughters, Sylvia and Monica, were found inside their Oakland Avenue apartment on Jan. 14. The discovery of the ATM withdrawals "certainly corroborates" the theory that the slayings took place during a robbery, DeFazio said. "That would be the inference based on the circumstances," he said. Many ATMs are equipped with video cameras, but DeFazio declined to say whether investigators had obtained photos or video of the person, or people, who used Armanious' card. He also would not say when investigators first discovered the ATM card had been used.
