WOODBURY - The former manager of a Hauppauge medical facility has been charged with ripping off dozens of brain-injured patients. Authorities say Benjamin Achampong allegedly stole the identities of more than 50 patients at the Long Island Head Injury Association. They say the 31-year-old African immigrant worked there from 2006-2007 and used patients' names and Social Security numbers to file false tax returns. Investigators say they believe the suspect then sent the money to at least 12 different bank accounts in his name, and ran a similar scheme in New Jersey that landed him $150,000. According to Nassau County District Attorney Kathleen Rice, Achampong stole more than $20,000 from patients at a Glen Cove group home back in 2009. He pleaded guilty in that case and was sentenced to five years probation. He is currently being held on $50,000 bail. Prosecutors: Coram man stole from deceased
