GREENFIELD, Iowa (AP) - Officials have urged people not to drink tap water in a southern Iowa community because they suspect an algae toxin has tainted the supply. Greenfield Municipal Utilities has announced that microcystin was potentially detected in the drinking water and that a sample was sent Tuesday for testing. The Des Moines Register reports that the toxin is produced by blue-green algae. A main source of Greenfield city water comes from Lake Greenfield, which has been experiencing an algal bloom.

IOWA CITY, Iowa (AP) - Authorities have recovered a man's body from the Iowa River in downtown Iowa City. Pedestrians on a bridge spotted the body amid tree branches around 12:30 p.m. Tuesday. Sheriff's deputies used boats to take the body to shore. The body has yet to be identified.

DES MOINES, Iowa (AP) - A judge won't provide immunity for a man who says Iowa's "stand your ground" law should protect him from prosecution following a Cedar Rapids gunbattle between two men. Michael Hodges Jr. and Zevon Johnson had both said the law made them immune from prosecution. Johnson has since pleaded guilty to a misdemeanor weapons charge. The Des Moines Register reports that a judge who is refusing to dismiss Hodges' charges says the law lacks a procedure to determine whether Hodges should receive immunity.

JEFFERSON CITY, Mo. (AP) - Missouri has revoked the peace officer license of a former highway patrol trooper who was driving a patrol boat when a handcuffed Iowa man fell out and drowned. The Kansas City Star reports Anthony Piercy's peace officer license was permanently revoked after the Missouri Department of Public Safety reviewed evidence in the death of 20-year-old Brandon Ellingson, of Clive, Iowa, on the Lake of the Ozarks in 2014.
