A man wanted in connection with a murder last December is back in Davenport.
Darius Johnson, 21, was booked into the Scott County Jail Monday night. He is charged with First Degree Murder and Willful Injury.
Johnson was arrested in Gary, Indiana last Thursday.
He is the third suspect arrested for the murder of Robby Kohn. Kohn was found shot in the head in a farm field off Utah Avenue.
Police say Kohn was brought to the site and killed by Johnson, Jessica Loerzel, and Barry Hamilton. Loerzel and Hamilton were arrested and charged shortly after the murder.
