JEFFERSON COUNTY — The Jefferson County jury that started hearing arguments February 20, in the murder and robbery case of a 21-year-old Mt. Vernon man returned a verdict Thursday afternoon of guilty on all counts.

According to the Jefferson County State’s Attorney’s Office, John Wells was found guilty on all counts of armed robbery and first-degree murder against him.

Prosecutors say DeAndrey Jackson was shot to death January 20, 2017, during a botched robbery in a Mt. Vernon alley.

Wells was subsequently indicted in the case, along with seven others, including Curtis Devan, Jr., Dantrez Brown, Deon Frazier, Jarron Liddell, Lamar Williams Jr., Tony Feggins, and Lekedrion Russell.

Russell, Devan, and Frazier have pleaded guilty to lesser charges in exchange for testifying against the other co-defendants.

Brown and Liddell also entered plea agreements requiring them to testify but murder and robbery charges against them were dismissed.

Williams, Russell, and Devan were all transported this week from the Illinois Department of Corrections to the Jefferson County Jail to make them available for testimony in Wells’ trial.

A status hearing on sentencing has been scheduled for 2 p.m. March 20.
