The woman who was killed had reported to police that her cop ex-boyfriend had been harassing and stalking her for nearly a year.

Ricardo Jorge Santos, with the New Jersey State Police, is accused of shooting Semanchik and Webb before killing himself, prosecutors said. He was found dead in a white Mercedes SUV parked in Piscataway. A gun was located inside the vehicle, the release stated.

An investigation into the shooting deaths of two people and the apparent suicide of a suspect, a state trooper, “raised serious concerns” from the county prosecutor’s office.
