OMAHA, Neb. (AP) — Normally this time of year, huge barges can be seen chugging up the Mississippi River, carrying grain to market and bringing agriculture-related products to farmers in the Midwest for the new growing season. But historic spring flooding has left parts of the Mississippi closed for business. The interruption is hitting an agriculture industry that’s already suffering, including from trade disputes that have helped drive down commodity prices.

KELLEY, Iowa (AP) — Law enforcement in central Iowa says one of three suspects has been arrested for a home invasion robbery last year in which an 82-year-old woman was sexually assaulted. The Story County Sheriff’s Office says a 17-year-old from San Antonio was recently arrested by police in Eagle Pass, Texas. Police continue to search for two other men.
