COLUMBIA — Police arrested a third suspect in connection with the shooting death of a Callaway County man that occurred on Conley Road in June.
Domionte Cheatum, 20, of Kansas City, is charged with second-degree murder, first-degree robbery and armed criminal action in connection with the death of Anthony Unger, 25, of Jefferson City.
According to probable cause statements filed in the Boone County Courthouse on Friday, the shooting of Unger occurred when Cheatum and another suspect, Samuel Butler, attempted to rob Unger during a drug deal.
Cheatum is the third man to be charged with second-degree murder in this case. Police arrested Butler and Joycelynn Brown in June; they were charged with second-degree murder in connection to Unger's death.
After her arrest, Brown told investigators that she had traveled with Unger to Columbia so he could sell a half-pound of marijuana to a man investigators later identified as Butler for $1,400, according to court documents.
According to the probable cause statement, based on interviews with Butler and another unidentified man, Cheatum is suspected of shooting Unger during the attempted robbery.
While court documents revealed that neither Butler or Brown were suspected of having shot Unger, according to the Revised Statutes of Missouri, a person can be charged with second-degree murder if the individual knowingly causes the death of another individual or if someone dies during the perpetration or attempted perpetration of a felony.
