CHICAGO — Students at a Far South Side high school were on campus Monday to mourn the fatal shooting of a college-bound senior.

Family and friends attended a vigil for James Garrett at Butler College Prep, 821 E. 103rd St. The 18-year-old was at a candlelight vigil on the Far South Side near 132nd Avenue and Prairie Street Saturday, where a large crowd had gathered to remember a woman killed in a car accident. Then around 7:30 p.m., there was an argument and a man and a woman pulled out guns, according to witnesses.

Gunfire erupted, and three people were shot: a 20 year-old-woman, a 48-year-old man and James, who was shot in the back and taken to the University of Chicago Medical Center in serious condition. He was later pronounced dead.

“The Light of James hasn’t gone out,” one mourner said in a speech to the crowd gathered at the school.

Garrett was full of joy, loved to dance and wanted to be a teacher. As a student at Butler College Prep, he had a 3.9 GPA and was the first in the Class of 2019 to be accepted to college.

“My son had everything going for himself, he wasn’t in no gang or none of that. My son was getting ready for prom and graduation he was so excited,” Brandy Colbert, Garrett’s mother, said.

“I feel broken; I don’t know if I’m coming or going, but I can’t cry because all I have is good memories with him,” Latasha Garrett, his sister, said.

Butler College Prep posted about the his death on their Facebook page , saying: “We will never forget how he loved Butler and everyone he met.”

Sunday night, his family and friends returned to the scene for another vigil, to pray in support of each other; and to remember. Colbert said she moved out of this neighborhood two years ago to keep her kids safe.

Area South detectives are investigating. No one is in custody.
