WATERLOO, Iowa (AP) — A Waterloo woman has been charged with murder in the house fire deaths of a mother and her son. The Waterloo-Cedar Falls Courier reports police on Monday charged 41-year-old Denise Susanna O’Brien with two counts of first-degree murder. The charges stem from an April 22 house fire that killed Ashley Smith and her 9-year-old son, Jaykwon Sallis. Court records show a restraining order barred O’Brien from going to the house, where she was involved in a dispute with a resident.

DES MOINES, Iowa (AP) — The Iowa State Fair has set a record for attendance at the annual 11-day event in Des Moines. Fair officials say an estimated 1,130,260 people attended the fair that ended Sunday. That topped the previous record set in 2017 by 189 people. Attendance was a bit behind the 2017 mark but moved ahead thanks to pleasant weather over the weekend. The fair also set a record for Grandstand concert attendance, with the biggest draw being the 15,775 people who attend a Thomas Rhett concert on Aug. 15.

OSKALOOSA, Iowa (AP) — Racers and others have been answering the call from an 11-year-old Iowa boy who wants auto racing stickers to cover his casket after he dies from leukemia. Caleb Hammond’s uncle, Chris Playle, told The Des Moines Register that his family brought him home to Oskaloosa after determining that the painful hospital treatments he’d been undergoing weren’t working and other options offered little hope. He says the stickers pouring in from social media appeals have helped keep everyone’s spirits up.
