DES MOINES, Iowa (AP) — More than 1 million doses of coronavirus vaccine have been administered in Iowa, even as residents who qualify struggle to make appointments for a shot. The Iowa Department of Public Health said Friday that Iowa has administered 1.03 million doses. The milestone reflects significant increases in vaccine supplies but it’s unclear how the state will handle surging demand as more adults become eligible in the coming months. Iowa has no centralized system for people to secure a vaccine appointment.

Iowa City (AP) — As virus cases plummeted, Iowa quietly extended a $3.9 million contact tracing contract with a company owned by a major Republican Party donor and supporter of Gov. Kim Reynolds. The Iowa Department of Public Health hired MCI, an Iowa City telemarketing firm, in November to trace the contacts of Iowa residents infected with COVID-19 after a one-day emergency bidding process. The two-month, $2.3 million contract came during an explosion of cases that filled up hospitals with patients and after counties had for months complained of a shortage of contact tracing workers. Four days before MCI’s contract was to expire on Jan. 31, Iowa’s state epidemiologist signed a three-month contract extension with MCI that is worth another $1.6 million.

MASON CITY, Iowa (AP) — Police in northern Iowa are investigating the discovery of what appear to be human bones. Mason City police said in a news release that a resident found the bones, along with clothing, on Thursday on the shore of the Winnebago River. Officers searched the area and found additional bones. Everything that was collected was transported to the Iowa Office of the State Medical Examiner for examination.

SIOUX CITY, Iowa (AP) — A Sioux City man has pleaded not guilty to first-degree murder in the shooting death of another man last year. The Sioux City Journal reports 36-year-old Roderick Banks entered the written plea Friday in Woodbury County District Court. He’s been charged with the murder count and a count being a felon in possession of a firearm for the Nov. 1 shooting death of 33-year-old Solomon Blackbird near Park Place Apartments in Sioux City. Prosecutors say Banks confronted Blackbird and Blackbird’s girlfriend outside the apartment complex and shot Blackbird once in the chest. Police believe the shooting was related to a drug deal. Investigators say they recovered a handgun believed to be the murder weapon.
