NYC woman: I covered for boyfriend in DWI 19 (UPI) -- A young woman was prepared to take the fall for a drunken car crash until her ex-boyfriend reneged on a promise to pay her expenses, the New York Post reports. Sophia Anderson, 21, who lives in New York City's Brooklyn borough, no longer faces a charge of driving while intoxicated, the Post reports. She can expect to be charged with obstruction of justice, sources told the newspaper Tuesday. Anderson and Dan Sajewski, 23, of Riverhead, N.Y., were in his father's Mercedes convertible when the car struck a house in Huntington, N.Y., in May. Anderson's lawyer said both were drunk and Sajewski, who had previous arrests for drinking in the subway and possession of marijuana, convinced his then-girlfriend to tell police she had been driving. Sajewski backed out on a promise to pay Anderson's legal expenses and take her on a vacation, the Post's sources said. "She was very intoxicated but she remembers him coming up to her after the crash and giving her a hug and saying he loved her and she had to do this for him," her lawyer, John LoTurco, said. It's the ultimate betrayal of trust. LoTurco told the Post police have confirming evidence Sajewski was driving, including his DNA on the airbag on the driver's side of the car. He said Anderson is cooperating with prosecutors, has broken off her relationship with Sajewski and is in rehab.
