DAVENPORT, Iowa — A fifth suspect in the shooting death of a man during a 2017 robbery has been found guilty of murder and robbery.

Christopher Dixon was found guilty in court Friday, October 18 on three charges related to the Sept. 22, 2017, shooting that killed 20-year-old Brady Tumlinson and injured Tumlinson’s girlfriend.  According to First Assistant County Attorney Amy DeVine, Dixon was found guilty of first-degree murder, first-degree robbery, and conspiracy to commit a forcible felony.

Dixon had previously entered a not guilty written plea to the charges in the case.

Two other men, 22-year-old Tristin Alderman and 21-year-old D’marithe Culbreath, were sentenced to life in prison earlier this year in the case. In December, 22-year-old Nakita Wiseman, was sentenced to 35 years for his role.

In early June, 19-year-old Darrell Williams Jr., of East Moline, Illinois, pleaded not guilty to first-degree murder and other counts.
