When the officers arrived at the house they allowed the man's female acquaintance to get dressed. As they waited the woman suddenly appeared and opened fire, wounding one of the officers. The male suspect then held the other officers at gunpoint and ordered them away. As they left he pushed his gun into Sergeant Black's chest. As Sergeant Black attempted to push it away he was shot. Patrolman Weir ran into another room where he was shot and killed by the female suspect. Both suspects were arrested and sent to trial only a few days later.
