Videos Show Exchange of Gunfire at Houston Megachurch

Just before opening fire with an assault-style rifle in the lobby of a Houston megachurch this month, Genesse Ivonne Moreno walked around the side of her sport utility vehicle and opened a rear passenger door for her 7-year-old son, who got out of the vehicle and followed her into the church.

Moments later, as deafening gunfire erupted in the church, the boy stood in an alcove with his hands pressed to his ears, according to surveillance and body-camera videos released on Monday by the Houston Police Department. At one point, the boy appeared to reach up for Ms. Moreno, as if asking to be picked up.

Later, he could be seen lying motionless on the carpeted hallway floor after being shot in the head.

The videos provided a clearer picture of the Feb. 11 shooting in Lakewood Church, one of the nation’s largest megachurches, led by the televangelist Joel Osteen. But they did not provide a complete account of what took place.

And they did not show the boy being struck, leaving open the question of who shot him. He remained hospitalized in critical condition with a gunshot wound to the head, officials said.
