A New York school safety officer who worked on the side as a plus-size model was fatally shot by her boyfriend, who then turned the gun on himself as the couple were celebrating his birthday, police said Monday.

Naire McCormick, a 44-year-old mom, was found with a gunshot wound to the head around 11:45 p.m. Sunday in a Brooklyn apartment, police said.

McCormick’s boyfriend, 47-year-old Jancy Dempster, is suspected of having shot her before killing himself, police said. Dempster’s cousin and McCormick’s son were in the other room and fled into the hallway when they heard gunshots, according to police sources.

Officers arrived on the scene after receiving a 911 call around 11:20 p.m. regarding somebody being harassed, The New York Daily News reported. McCormick and Dempster were pronounced dead at the scene. Police said a gun was found near Dempster’s body.
