A drunk off-duty Jersey City cop has been revealed to be the driver of an early Saturday morning hit and run near Battery Park City that killed one woman and left her boyfriend in critical but stable condition. 25-year-old Martin Abreu, a fourth year officer, was charged with vehicular manslaughter and assault and driving while intoxicated. He has also been suspended without pay. 26-year-olds Marilyn Feng and Dennis Loffredo were struck at around 3:40 a.m. on their way home from a night of dancing. They had been taking tango lessons weekly and parents of Loffredo thought that the two would get married. Loffredo's mother donates to Mothers Against Drunk Driving. She told the News, "I think next year I'm going to donate even more."
