IOWA CITY, Iowa (AP) — Iowa has reported its biggest daily increase in coronavirus cases yet, as dozens more employees at a large pork plant tested positive and the number of outbreaks at long-term care facilities doubled. Gov. Kim Reynolds on Tuesday announced 189 new cases of COVID-19, the respiratory illness caused by the virus. The total number of patients hospitalized with the virus in Iowa increased by 14% from a day earlier, to 163, and deaths grew by six to 49. The governor said 86, or nearly half of the new cases, were related to the outbreak at the Tyson Foods plant in Columbus Junction.

O’FALLON, Mo. (AP) — The nation’s two largest rivers top a new listing of the most endangered waterways. The Washington, D.C.-based conservation organization American Rivers on Tuesday released its list of the 10 most endangered waterways in the United States. The Upper Mississippi River was cited as the most endangered, followed by the lower Missouri River. For both rivers, American Rivers cited increasingly severe flooding driven by climate change. Extreme flooding has become increasingly common on the Upper Mississippi. Meanwhile, parts of the Missouri River saw record and near-record flooding last spring in Missouri, Iowa, Kansas and Nebraska.

DES MOINES, Iowa (AP) — A newly-released report by the Iowa State Auditor says a former Buffalo city employee failed to deposit more than $42,000 in collections over a three-year period into the city’s bank account. The audit says the special investigation was prompted by a request from Buffalo city officials who had concerns about transactions processed by the former Deputy City Clerk Riki Harrington. The audit found $42,390 in undeposited collections from April 2015 through August 2018. That amount included $28,039.42 of checks substituted for cash collections recorded in the city’s accounting system but not deposited, as well as $5,079 in utility customers’ payments and $3,600 in utility security fees not deposited.

WATERLOO, Iowa (AP) — Police in northeastern Iowa say a one-time boxer and suspect in a deadly, botched armored car heist last month is now charged in a fire that destroyed a well-known Waterloo restaurant. The Courier reports that 29-year-old Kevin Cruz Soliveras was arrested Monday on arson and burglary charges in the March 5 fire that gutted the Wishbone Restaurant and Bar. Police say security video shows Cruz and another person breaking into the restaurant and coin-operated machines there before setting fires in the restaurant. Days later, police say, Cruz was part of a group that hatched plan to rob an armored car outside a Waterloo bank. The robbery failed when guards opened fire, wounding Cruz and another man and killing Bryce Miller.
