Investigators are looking into the cop sister of accused killer quack Dean Faiello to determine if she helped cover his tracks after he allegedly killed investment banker Maria Cruz during botched laser surgery, according to law-enforcement sources.
Manhattan District Attorney's Office detectives are eyeing Debra Faiello, a New Jersey state trooper, to see if she took key evidence and set up his life as a fugitive in Costa Rica, the sources said.
After her brother bolted, Debra removed his patient files and a bag of his possessions that contained Cruz's ID, keys and credit cards, sources involved in the case said.
She took her brother's SUV, which cops think he used to transport Cruz's body. And she pressured her brother's attorney to wire him $50,000 in February 2003, two weeks before Cruz's remains were discovered at Dean's Newark house, the sources said.
At the time, the attorney didn't know Dean was in Costa Rica. When he asked Debra where her brother was, she told the lawyer he "didn't want to know," one source said.
The exchange has raised suspicions among investigators who previously said Debra was not implicated in the case although one law-enforcement source said she "should have been looked at more closely."
