Waukesha County prosecutors said it started at a house party on nearby Wisteria Lane. Tronco and another man started arguing, and it continued outside the apartment building – with punches. Police said Tronco got into Williams' Jeep and drove after the other man.

"(Tronco’s) response, according to the complaint, was to get with his friend, grab the firearm out of the glove compartment and start shooting at the car to the point the other person was hit," said Court Commissioner David Herring said.

"Mr. Tronco has a track record of just violence, period. The allegations are (Williams) helped facilitate another individual shoot at somebody multiple times, and really had the ability to stop the whole altercation."
