A plea deal was reached two weeks ago. In exchange for pleading no contest to a misdemeanor charge of OWI, prosecutors planned to dismiss the 28 felony counts of second-degree recklessly endangering safety charges. The state recommended 60 days in jail. 

Defense weighs in

What they're saying:

Defense attorney Anthony Cotton said the plea would have avoided a trial and the need for children to testify. 

"He wasn’t drunk. He wasn’t under the influence of drugs. He had some Robitusin DM in his system and a therapeutic level of anti-depressants," Cotton said.

Cotton said Cunningham has no prior criminal record and was a "beloved driver." The defense attorney said it was a new bus route that January day, Cunningham missed some stops, and the children on the bus became unruly.

Newly released 911 audio reveals panic during a January 2025 Hartland bus ride that led to OWI and 28 endangerment charges against 73-year-old driver Walter Cunningham.

Cotton said Cunningham failed field sobriety tests because he was 71 years old at the time, and had a double knee replacement. 

Prosecutors said Cunningham shouted at the children, saying things like, "I am God on this bus." 

Court appearance on March 2

Local perspective:

In court on Monday, March 2, prosecutors rescinded the plea deal, saying parents wanted to talk to the district attorney first before an offer was put on the table.
