A woman in a trench coat armed with a long rifle – and accompanied by a young child – entered pastor Joel Osteen’s Lakewood Church on Sunday afternoon and began firing, Houston Police Chief Troy Finner said, Paralel.Az reports citing CNN.

Two off-duty law enforcement officers – a Houston police officer and an agent with the Texas Alcoholic Beverage Commission – engaged and struck the woman, who died on the scene, Finner said. The woman was roughly 30-35 years old, the chief said.

“Unfortunately a 5-year-old kid was hit and is in critical condition at our local hospital,” he added. The incident unfolded just before 2 p.m., the chief said. It was unclear who fired the shot that struck the child, the chief said, or what the child’s relationship to the shooter was.
