A Knoxville man accused of killing his mother in 2015 will get a new trial next month in Council Bluffs.  Marion County District Court records say a judge on Tuesday (1/29) ordered the trial of 46-year-old Jason Carter to start March 4 in Pottawattamie County. The change of venue had been granted because of pretrial publicity.  In December 2017 Carter was charged with first-degree murder, accused of fatally shooting 68-year-old Shirley Carter in June 2015 in the kitchen of her rural Knoxville home. The charges were filed two days after a jury found him civilly liable and ordered him to pay $10 million to his mother’s estate.  Bill Carter had sued his son for wrongful death, saying his son was financially strapped and killed Shirley Carter to gain access to his parents’ $10 million in assets. Jason Carter has denied that.
