ROCKFORD, Ill. (AP) — The mother of a driver shot to death during a traffic stop has filed a lawsuit against the city of Rock Falls and a police officer.

Nathaniel Edwards of Sterling was shot several times in the back and killed Friday in the driveway of a Rock Falls home after a police pursuit.

Sauk Valley Media reports in a lawsuit filed Tuesday in federal court in Rockford, Alfredia Edwards of Chicago claims the shooting was "unjustified," ''excessive and unreasonable."

Investigators say the 43-year-old Edwards at first refused to stop the vehicle, then when he did stop, did not respond to verbal commands to get out. Authorities say he put the car in reverse and accelerated toward the officer who shot him several times.

The lawsuit seeks more than $1 million in damages, and requests a jury trial. Rock Falls city attorney James L. Reese has not commented on the lawsuit.

Iowa man pleads not guilty in shooting death of mother

KNOXVILLE (AP) — A southern Iowa man has pleaded not guilty to a murder charge stemming from the death of his mother.

Court records say 45-year-old Jason Carter entered a written plea Wednesday in Marion County District Court. A trial date has not been set.

In December a jury found Carter civilly liable for the June 2015 shooting death of 68-year-old Shirley Carter at her home in Knoxville. Carter and his father, Carter, blamed each other for the woman's death. Bill Carter filed a wrongful death lawsuit against his son, and the Marion County jury found in the older man's favor, ordering Jason Carter to pay $10 million to her estate.

Iowa department reports norovirus outbreaks

DES MOINES (AP) — The Iowa Department of Public Health says it's received numerous reports of norovirus illnesses in the past few weeks.

Norovirus cases occur all year but are usually higher in the colder months because people are indoors more and in closer contact.

The virus spreads easily when people don't stay at home with diarrhea or vomiting and when they don't wash their hands after going to the bathroom. The illness also spreads when people prepare food while ill with vomiting and diarrhea.

The state medical director says people with diarrhea or have been vomiting should not handle food, no matter how well they wash their hands.

Norovirus symptoms include nausea, vomiting, diarrhea and low-grade fever.

University of Illinois launches bioenergy research center

CHAMPAIGN, Ill. (AP) — The University of Illinois is launching a new bioenergy research center that will be used to generate new fuel products directly from plants.

The new Center for Advanced Bioenergy and Bioproducts Innovation is a collaboration with the Carl R. Woese Institute for Genomic Biology, where it will be housed, and the Institute for Sustainability, Energy and Environment.

Biology professor Evan DeLucia will direct the center. He tells The News-Gazette that scientists from the university's multiple disciplines will partner with 17 institutions on the project aiming to reduce the nation's dependence on fossil fuels. Some of the partners include Iowa State, Princeton, Mississippi State, West Virginia and Boston University.
