In late June 1987, the town of Bemidji, Minnesota, was gearing up for Independence Day weekend. Celebrations quickly turned to panic when Anita Carlson, a college graduate with hopes of working in TV production, went missing from her nighttime job at Pete’s Place, a convenience store at the intersection of Highways 2 and 89. By the end of the weekend, Anita had been found dead. Nearly 40 years later, investigators are still trying to figure out what happened that night.
