A Springfield, Massachusetts cop was shot and killed by a New York City Corrections officer Monday, cops say.
Kevin Ambrose was responding to a call at the home of Charlene Mitchell, 29, who said her crazed ex-boyfriend was there and that she feared for her life, CBS reports.
Ambrose arrived to find Mitchell and the Corrections officer, Shawn Bryan, arguing outside. Minutes earlier, Mitchell had obtained a restraining order against Bryan.
Springfield Police Commissioner William Fitchett explained that Bryan then pushed Mitchell inside the house before turning around and shooting Ambrose through the door. He then opened the door and fired at Ambrose again, before shooting Mitchell and returning to his car, where he turned the gun on himself, firing a fatal shot into his chest.
Mitchell and Bryan's one-year-old daughter was in the home during the time of the shootout.
Both Ambrose and Bryan died from their injuries. Mitchell is in critical condition.
Mitchell had agreed on the restraining order to allow Bryan to visit his daughter. The order details, however, some scary text messages from Bryan.
He told her he "wanted it to be about the child and nothing else," referring to their 1-year-old daughter. Mitchell said she agreed but when he asked if he could talk to her, she said, "I have nothing to say to you."
That's when he allegedly sent text messages saying, "I'm going to make you wish you were not born," according to the restraining order application.
Mitchell also wrote in her restraining order application that Bryan, a guard on Rikers Island, "had always told me that he is crazy and that his head is not good."
Kevin Ambrose was a 36-year veteran of the police force.
Hampden District Attorney Mark Mastroianni said Ambrose's "career choice made him a hero,” and, that “his actions today made him a hero.”
