The first of four defendants facing charges in connection with the shooting that injured Independence Police Officer Tom Wagstaff is scheduled to go on trial next week.

Donald Nussbaum, 52, of Kansas City, faces charges of first-degree robbery, burglary and kidnapping and armed criminal action. He and a co-defendant allegedly drove two other co-defendants to the Independence area where they later burglarized a house and tied-up the homeowner on March 29, 2017.

When Wagstaff and other officers responded, the burglars drove the victim's car through the garage, and Wagstaff was gravely injured during the ensuing gunfire.

James McChan, 57, faces the same charges as Nussbaum, is scheduled to go on trial June 25. Ronar Santiago-Torres, 28, also faces those charges, in addition to first-degree assault and resisting arrest. He is scheduled to go on trial July 9. Joseph Wyatt, 29, faces the same same charges as Santiago-Torres, in addition to attempted robbery, tampering with a motor vehicle, attempted robbery and an additional count of armed criminal action. His trial is scheduled to begin June 11.

All four defendants are in jail on cash bonds of $500,000.

Nussbaum is the son of the burglary victim's friend who had seen the home invasion via video feed and called police, according to court documents. He told police he and McChan had driven Wyatt and Santiago-Torres to the area knowing they planned to rob somebody and obtain a safe combination. He said he specifically had told them not to rob the victim's house, knowing it had surveillance.
