Amid the investigation into the double murder-suicide carried out by a New Jersey state trooper, the Franklin Township Police Department has been taken over by the prosecutor’s office.

Two top cops in New Jersey have been placed on leave after the murder-suicide that claimed the life of beloved veterinarian Lauren Semanchik and her new boyfriend raised “serious concerns” about the department’s operations.

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.
