The Isabella County Sheriff's Department said that the two salesman knocked on the door of a home in Fremont Township, where the suspect gestured from inside the home to indicate that he would attend to them in a moment.
The salesmen became suspicious when the suspect walked out of the home to his garage, however, and decided to leave. The suspect then allegedly fired two shots with a 20-gauge shotgun as the men drove away, according to the sheriff's department.
No one was hurt in the incident. Investigators believe alcohol could have been a factor, the sheriff's department said, and the suspect faces charges of assault and reckless discharge of a firearm.
