Yager said after Jackson ordered everyone out, an argument ensued and several shots were fired. Jackson said more than one person was firing, but they haven’t located any other shooter other Jackson. During the brawl, Jackson shot Hickman of Alton.

Jordan will have to serve at least 50 percent of the 20 years for murder plus a consecutive six years at 85 percent for the aggravated battery charge.

Jordan has a prior conviction for theft and another conviction for burglary.

At the time of the killing, Hickman had been released on leave after being sentenced to two years in the Illinois Department of Corrections on a charge of aggravated domestic battery. Hickman has convictions for retail theft, two counts of violation of probation, and three misdemeanors.

Yager said during the brawl somebody punched Jackson. The state and the defense agreed that Jackson believed he had to fire the shots in self-defense but his belief was unreasonable.
