Just days before a Missouri mother and her two children were murdered by her estranged husband, the mom posted online about the horrific abuse she endured at the hands of her killer, according to a report.

Roseann McCulley, 34, recently posted on Facebook that her husband Bobby McCulley, 35, beat her up so badly she was hospitalized, and he “was able to stomp my chest and abdomen, so the bruising and swelling is really bad there,” KMOV reported.

A week later, her husband reportedly wrote on her page, “Everyone enjoying the show! More to come.”

Friend Stephanie St. John recalled to KMOV she told Roseann to take the children and “leave the house” last Thursday — but it was too late.

“I called her so many times last night and I didn’t get a response back,” St. John said.

It wasn’t until the following morning she learned her friend and her two children, son Kayden Johnson, 13, and daughter Kaylee Brooks, 6, were killed.

Cops say Bobby McCulley fatally shot the family on Thursday, five days after his wife filed for divorce, according to the St. Louis Post-Dispatch.

Bobby McCulley also took the couple’s 1-year-old daughter, prompting authorities to issue an Amber Alert. He dropped her off with family unharmed, cops said.

Police discovered the family inside their home outside of St. Louis on Friday. That same day, cops found Bobby McCulley had fatally shot himself inside a car in St. Louis’ Old North neighborhood.
