MCKEESPORT, Pa. — A Pennsylvania woman is accused of killing her 17-month-old son and sending video of the dead child to the boy’s father, who she had been fighting with, police said.

On Tuesday, officers arrested Christian Clark, of McKeesport, and jailed her on multiple charges, including criminal homicide.

Clark sent several texts to the boy’s father during the dispute, according to the Allegheny County police, including “Ya kids ain’t safe here I don’t want them here” and “I’m killing them” — complete with a laughing emoji.

Clark believed her boyfriend was cheating on her and threatened to take her anger out on the children, the Pittsburgh Post-Gazette reports.

Clark sent photos of the children face down.

The affidavit shows she then sent a video and a text saying “I wasn’t even gonna send you videos but pretty sure ya son is legit dead so…im going to jail either way hope it was worth it.”

Police said a girl was also featured in the video, but that child is alive.

Clark was awaiting her arraignment as of Wednesday afternoon.
