MABLETON, Ga. — Michael Sumler, a longtime member of the iconic funk band Kool & the Gang, died Sunday night in a crash on Veterans Memorial Highway in Cobb County. He was 71.
Known to fans as “Chicago Mike,” Sumler was driving a black 2014 Nissan 370Z around 11:35 p.m. when the car crossed into oncoming traffic and collided head-on with a 2025 Kia Sorento near Buckner Road, according to the Cobb County Police Department.
