David Kaiser, co-founder of a onetime flourishing Twin Cities-based video store chain, has been the subject of a missing-person search in his adopted state of Montana since late last month, according to authorities.

Kaiser, 53, was last seen June 28 in west-central Montana and may be traveling in his SUV, said the Ravalli County Sheriff’s Office.

He opened his own cafe in Victor, Mont., just two days earlier, according to his family in Minnesota. He was reported missing on June 29, when he failed to show up that morning at the cafe, his family added.

Kaiser moved from his lifelong hometown of Edina four years ago, about the time he divorced, and ran for the U.S. House in Montana in 2012 as a Libertarian Party candidate.

He and one of his brothers founded Mr. Movies. It grew from one store to the fourth-largest privately owned video chain in the nation. The Eden Prairie-based business was eventually bought out, but there are some Mr. Movies stores still operating independently.

Kaiser, who has two grown children and three brothers in the Twin Cities area, is described as white, 5 feet 4 inches tall and about 200 pounds. He has blond hair and hazel eyes. He was last seen wearing a dark blue polo shirt, bluejeans and red and white tennis shoes.

The Sheriff’s Office said he may be traveling in his black and silver 2005 Chevy TrailBlazer, with Montana Patriot-style license plates NNBBOO.

Anyone with information about his whereabouts is asked to call the Sheriff’s Office at 1-406-363-3033.
