Ohio police have released a heartbreaking 911 call from a woman after a fatal shooting involving her two young children.

“There’s been an accident with a weapon….My daughter’s been shot with a gun,” a distraught Mary Massuros said in the Saturday call, according to the Columbus Dispatch.

The paper reported that as screams are heard in the background, Massuros then says to someone else in the house, “Oh my God, Oh my God! Stop! Why did you have a gun in the house? ... I told you this would happen.”

The paper reported that Massuros’ 2-year-old daughter was killed after being shot by her 6-year-old brother in their home in Pataskala.

Authorities identified the girl as Noel Massuros and said she was shot in the head.

Massuros told the 911 dispatcher her daughter just turned 2 the day before, according to the paper.

The paper also quoted her as telling the dispatcher as she administered CPR, “This happened a while ago….I thought it was something else.”

She then explains the shooting happened two hours earlier and that she was calling after discovering what happened, according to the paper.

Fox 28 Columbus reported that during the 911 call Massuros says that “some f------ idiot” had left the gun out, which her son found and was playing with.
