A pickup truck went through a stop sign in rural Michigan and crashed into a van carrying members of an Amish community, killing at least six people, authorities said.

The crash occurred Tuesday afternoon in Tuscola County’s Gilford Township, 100 miles north of Detroit.

Thirteen people were in the two vehicles, including 10 in the van, the sheriff’s office said.

“Multiple passengers were ejected from the van and the pickup,” the sheriff’s office said on Facebook. “At this time there are 6 confirmed fatalities and the condition of the additional patients is unknown.”

Members of a local Amish community were in the van, Undersheriff Robert Baxter said Wednesday.

“They had a paid driver in the van,” he told The Associated Press. “I’m not sure where they were headed or where they were coming from. They’re county residents.”
