An Iowa man who was found responsible for his mother's death at a civil trial but acquitted at a murder trial is now suing criminal investigators and his father.
Forty-seven-year-old Jason Carter filed a federal lawsuit Thursday accusing investigators of conducting a biased and incomplete investigation into his mother's death.
Carter's father, Bill Carter, won a wrongful-death lawsuit against his son in 2017. The suit alleged that Jason fatally shot 68-year-old Shirley Carter in June 2015 to gain access to his parents' assets.
Jason Carter was ordered to pay $10 million to his mother's estate. In March, a jury acquitted him of murder.
