A Granite City man has been sentenced to 33 years in jail for the murder of his estranged wife in 2013. 45-year-old Tyrone Stainback pleaded guilty to first-degree murder and was sentenced in Madison County Court yesterday in the death of 34-year-old Marissa Stainback of Alton.
On June 11, 2013, Tyrone Stainback attacked his wife who was walking with a man on Northgate Industrial Drive in Granite City, stabbing her multiple times. She died later that day at Gateway Regional Medical Center. Tyrone Stainback was arrested shortly after the incident and claimed in the sentencing hearing yesterday that the victim had caused him pain during their marriage and divorce and he decided to kill her. An aunt of the victim is now caring for the couple’s two children.
