BURLINGTON, Iowa (AP) — Another person has been charged with killing a 26-year-old man in southeast Iowa. Authorities say 30-year-old Caesar “CJ” Davison, of Chicago, was served Thursday with an Iowa murder warrant as he was returned from Illinois. He’d been held in Illinois for a parole violation, and he denied while being questioned there that he was involved in the Iowa slaying.

Prosecutors say Davison conspired with four other people to kill Demarcus “Peanut” Chew, who was fatally shot in a car outside his mother’s Burlington apartment on Sept. 10, 2017. One of them, Antoine Spann, pleaded guilty last month and was sentenced to 20 years in prison after making a deal with prosecutors. Spann’s plea agreement says he must testify against any others charged in the slaying.
