DES MOINES, Iowa (AP) — Des Moines police have arrested a 52-year-old woman in the stabbing death of a man.

DES MOINES, Iowa (AP) — An overflow crowd jammed a legislative hearing to oppose a bill they argued would make it more difficult to ensure safe water. At Monday’s public hearing on a bill that would dismantle water utilities in Des Moines, West Des Moines and Urbandale, opponents criticized the proposed move from oversight by independent boards to city councils in the three cities. The move is largely supported by cities, but critics contend moving control away from independent water experts will lead to dirtier water.
