The FBI Minneapolis Field Office on Friday identified the man as 34-year-old Nathan Thoe from Hortonville, Wisconsin. The FBI says an arrest warrant had been issued for Thoe because he was the subject of an ongoing investigation.
Officials say federal officers from more than one agency were attempting an arrest at the White Lake rest area on Interstate 90 in South Dakota Jan. 13 when Thoe was shot and killed. Authorities have not said what prompted the fatal shooting.
The FBI says Thoe had been in and around Pierre in the past several months.
