ST. IGNACE — A Florida man was taken to the hospital after an 18.5-hour standoff with police in St. Ignace after they investigated a report of a subject in a commercial truck who was suicidal, according to the Mackinac County Sheriff’s Office.

Mackinac County Sheriff’s deputies responded to a St. Ignace truck stop to investigate the report around 7:20 p.m. Tuesday, police said.

Upon deputies’ arrival, it was determined that the subject was in possession of a loaded handgun. The man barricaded himself in the cab of the truck for 18.5 hours, according to the sheriff’s office.

Negotiations between the man and the police continued “on and off throughout the duration of the stand-off” with the man, with the subject “finally exiting the vehicle unarmed,” a press release about the incident states.

The man was “peacefully taken into protective custody” at 2 p.m. Wednesday and transported to the Mackinac Straits Hospital for a mental evaluation, police said.

The Mackinac County Sheriff’s Office was assisted by the Michigan State Police and St. Ignace police during the incident.
