Slain veterinarian Lauren Semanchik feared for her life and even spoke of getting a restraining order against New Jersey state trooper Ricardo Santos nearly a year before the deranged ex-boyfriend killed her in a sickening murder-suicide, text messages show.

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.

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.
