CHICAGO — A Chicago Public School teacher was shot and killed while driving on the city’s South Side Monday evening.

Quentine Carradine, 49, was traveling in a car westbound near the 400 block of East 87th Street around 4:07 p.m. when he was shot in the head by an unknown individual.

He was transported to the University of Chicago Medical Center in critical condition and was later pronounced dead.

He is being described as a loving and caring person who treated everyone like family.

He’s affectionately known as Mr. Quen to his many students and athletes who say he’s definitely leaving a lasting impression.

“He definitely had a big personality,” Kameryn Ivory, Carradine’s former student-athlete, said. “When you saw him coming down the hallways he had to make a joke and lighten up everybody’s day. He was just a great person to be around. He was a great person, a family man.”

Ivory was Carradine’s student-athlete from third to eighth grade, but they kept in contact for years to come.

It’s a similar scenario for many people who at some point crossed path’s with him.

He was more recently a special education teacher and a basketball coach at New Sullivan Elementary School.

“Don’t make it a sad time during this tragedy,” Ivory said. “Mr. Quen wouldn’t want everybody to be sad. He’s in a way in a better place now. But Just remember him as Mr. Quen, being the loving person that he was. The caring person.”

Chicago Public Schools released a statement that said:

“The Chicago Public Schools (CPS) community is deeply saddened by the tragic loss of Quentine Carradine… Our thoughts are with the Carradine family, their friends and the entire New Sullivan and CPS community during this difficult time.”

Carradine was a special education teacher and basketball coach at New Sullivan.

Police are currently investigating the situation as a homicide.
