In a meticulously premeditated attack, the lone murderer—dressed in black, armed with a rifle, shotgun, and pistol, and positioned outside the church—killed two children, injured 18 other people, and then committed suicide. The assailant had barricaded at least two exit doors from the outside with pieces of lumber. Witnesses say the attack lasted no more than two minutes. News reports do not indicate that a church security team was present.

Approximately 116 rifle ammunition casings, three shotgun shell casings, and one unfired pistol cartridge were recovered from the scene. The handgun appeared to have malfunctioned.
