A Lake County jury found a 25-year-old Michigan man guilty of killing a Zion man after a night of drinking and playing cards.
Terrance Scott, of Ypsilanti, was convicted of first-degree murder Thursday in the death of Prentiss Carter, 42, Lake County Assistant State's Attorney Scott Hoffert said.
Scott's prison sentence will be determined at an Oct. 6 status date in front of Lake County Judge Mark Levitt.
Hoffert said Scott had been acting aggressively toward Carter during the small gathering of friends and family at a house on Carmel Boulevard in Zion on Nov. 8. Prosecutors said Carter had been dating Scott's sister.
After most people had left or gone to bed about 1 a.m. on Nov. 9, Carter was shot near his forehead, Hoffert said.
A resident of the house awoke at the sound of the gunshot and called police, Hoffert said.
Scott left the house immediately after the shooting, Hoffert said, but was taken into custody minutes later a few blocks from the house.
Gunshot residue was discovered on Scott's clothes and on his left hand, Hoffert said.
