PEORIA - Authorities say a Peoria man has been convicted of first-degree murder in the death of a state lawmaker's son in 2014.
Jurors returned their guilty verdict against Sean Walls, 38, on Wednesday. Walls was accused of murder in the death of 22-year-old Derrick Booth Jr. last spring. Authorities say Booth died from a gunshot wound to the chest sustained during an argument with Walls.
According to prosecutors, Walls shot Booth to impress his friends, and because he was insulted that Booth refused to sell him any marijuana at a discount. However, Walls says he acted in self-defense after Booth pulled out a handgun.
