It took Anna about ten minutes to convince Bubich she was his wife. Anna asked him in to the living room where Bubich kissed her, his fifteen year old daughter, and his four year old godson. He asked for clothes and Anna brought him underwear, a shirt and a pair of pants. He became angry when she could not find a belt for the pants. He went to the back of the butcher shop and emerged with a sixteen and one-half inch butcher knife. He warned his family to keep still or he would kill them, changed his mind and told them to leave the room, and locked the door behind them. The upstairs neighbors heard the commotion and called the police.

 Sergeant Massey, Patrolman Messing and Patrolman Woerhaman responded to the butcher shop. They pled with Bubich to open the door but he refused. Officers called for back-up at which time Sergeant Schrank and Patrolmen Bonness and Wehegan arrived. Sergeants Massey and Schrank went to the back of the building to try a window. Wehegan and Bonness stationed themselves outside the kitchen door where Bubich barricaded himself. 

 Wehegan obtained the door key from Mrs. Bubich and unlocked the door. As Wehegan pushed it open and entered, Bubich thrust the knife into the officer's abdomen.  As Wehegan fell, he sprayed tear gas in Bubich's face, blinding him. Bubich dropped the knife and staggered through the door and down four steps to where Patrolman Bonness was standing with a shotgun. Bonness fired twice at the madman striking him in the arm and stomach.

 Bubich and Officer Wehegan were transported to the Lutheran Hospital. Bubich died moments after arrival and Officer Wehegan went to surgery. Doctors advised the knife severed his intestine in five places and there were several internal hemorrhages. At  1:30 pm, Officer Wehegan succumbed to his wounds.

 Robert Wehegan's name is inscribed on the National Law Enforcement Officers Memorial Wall, Washington, D.C. panel 29, west wall, line 9.
