ROCHESTER — Greg Sellnow, a longtime reporter, editor and columnist for the Post-Bulletin of Rochester, has died, the newspaper reported Sunday.

Sellow, 54, was driving home from the Minnesota state high school hockey tournament in St. Paul late Friday when he apparently had a medical emergency, Managing Editor Jay Furst said. The vehicle he was driving left the road and came to rest in a field. Passengers in the vehicle were not injured, the newspaper reported.

Sellnow was a Post-Bulletin reporter, editor and columnist for 26 years. He had been editorial page editor since 2007. He worked as a reporter in his hometown, Cape Girardeau, Mo., as well as Bismarck, N.D., before joining the Post-Bulletin in 1986 as a reporter.

Sellnow was a native of Brainerd and a 1980 graduate of the journalism program at the University of Missouri in Columbia.

He is survived by his wife, Shelly, and three children, Caitlin, Abby and Cam. Funeral arrangements are pending.
