In a murder-suicide incident, a woman and her two children were killed by her husband two days after she posted some disturbing messages on Facebook.

Roseann McCulley, her 13-year-old son Kayden Johnson and 6-year-old daughter Kaylee Brooks were fatally shot by her estranged husband on Thursday in Missouri, CBS/ABC-affiliated WJHL reported. The police arrived at the scene after receiving reports of a shooting, and found the bodies of the victims.

During the investigation, they learned the couple's 1-year-old child was missing from the home, Associated Press reported. The police then raised an Amber Alert, but later called it off Friday after they found the girl was dropped off at a relative's home.

The authorities then began searching for the accused, identified as Bobby McCulley III. By the time the cops traced him, Bobby had fatally shot himself. Before the accused was found dead, the police had charged him with three counts of murder, three counts of kidnapping, 1 count of burglary, and 7 counts of armed criminal action, WJHL reported.

During investigation, the police found Roseann had posted on Facebook about being abused by her husband. In the post she wrote Bobby "was able to stomp my chest and abdomen, so the bruising and swelling is really bad there." In another post she mentioned receiving morphine through an IV for the pain, WJHL reported.

A week later Bobby wrote on his wife's Facebook page, "Everyone enjoying the show! More to come."

Investigators believe Bobby held his family hostage in their own home, and later killed his wife and children.

In a similar incident in Oklahoma last month, a father killed his two teenage daughters before shooting himself. The mother of the teenagers reportedly received a call from her husband telling her he would kill his daughters and then himself. The woman then quickly informed the police about the call. Officers, who arrived at the scene, found the three bodies. The woman later revealed she and her husband were having marital issues.
