A Newton jury has convicted a man of helping his mother stab his wife to death in 2013.
Jurors handed over the verdict finding 40-year-old Dustin Jefferson guilty of aiding and abetting first-degree murder in the death of his wife.
His mother, Ginger Jefferson, is serving life in prison for first-degree murder in the September 2013 attack of 32-year-old Kerry O’Clair Jefferson.
The trial is the state’s third attempt to convict Dustin Jefferson. His first two trials were both in Tama County. The first ended during jury selection and jurors could not reach a unanimous verdict in the second trial.
The trial moved to Newton after a judge granted a change of venue.
