Concerns raised over a New Jersey police department’s handling of a deadly shooting that reportedly involved a state trooper has spurred a county prosecutor’s office to take over the force’s daily operations. Hunterdon County Prosecutor Renee Robeson announced the move Thursday, saying the police department’s chief and a sergeant had been placed on administrative leave by the town. Authorities have said a woman and her boyfriend were found shot to death in her Franklin home on Saturday. The woman’s ex-boyfriend is a 45-year-old state police lieutenant who was found dead later that day from a what authorities say was a self-inflicted gunshot wound.
