Oklahoma mother and her 3 children killed in murder-suicide during supervised visitation, police say

An Oklahoma mother is accused of killing her three young children, ages 11, 6, and 10 months old, and then herself during a supervised visitation at her home following an hours-long standoff with police.

An officer responded Thursday afternoon to a home in Verdigris, in the Tulsa metropolitan area, because fireworks were erupting outside, the Oklahoma State Bureau of Investigation said in a news release.

The officer encountered Brandy McCaslin, 39, barricaded inside the home with a firearm. State investigators said they tried to negotiate with McCaslin for the next three hours.

“After no response, officers made entry into the home where they found McCaslin, along with her three children, dead inside,” the bureau said. “It was determined that McCaslin shot all three kids and then turned the weapon on herself.”

The State Bureau of Investigation and the Verdigris Police Department did not immediately return a request for comment on Saturday.

Police Chief Jack Shackelford told the Tulsa World that a woman went to the home to drop off one of the children to McCaslin for a supervised visitation when McCaslin allegedly pointed a gun at the woman and took the child.

McCaslin then locked the woman and two other children in the garage, according to the newspaper. The woman used a firework to draw attention to the home and was able to escape with the help of officers, the police chief told the Tulsa World.
