Two other off-duty Mount Vernon police officers were also at the scene.Officers Burke, Bendo, Leonard Cooper and Robert Wuttke have all been place on modified duty. Police are investigating whether Bendo followed proper procedures. Meanwhile, police have been unable to locate the car involved in the accident.
