MONTROSE TOWNSHIP, Mich. -- The body of a Canadian man found in a landfill in Michigan likely came in a shipment of garbage, authorities say.

Kevin Joseph Arendt of Mississauga, Ont., was last seen leaving a bar June 27 near Dundas Street West and Confederation Parkway in Mississauga.

George Tudos, a Peel police spokesman, said it's strange that the 38-year-old's body was found in a landfill.

"Investigators are still trying to determine how he came to end up there," Tudos said.

Authorities in Michigan say they suspect Arendt's body arrived in a shipment of Canadian garbage. It was found Friday by a worker at the Brent Run landfill in Montrose Township.

The autopsy, conducted in the U.S., didn't reveal anything that appeared to be criminal in nature, Tudos said.

When Arendt first went missing, he was seen driving a navy blue Jeep Liberty with Wisconsin plates. But Tudos said that as far as he knows, Arendt was Canadian. He wasn't sure if the Jeep belonged to Arendt.

Although no foul play is suspected, Arendt's family told police that it was out of character for him to go missing.

The landfill is about 110 kilometres northwest of Detroit. The investigation is ongoing.
