CHICAGO  — The family of 15-year-old Sincere Cole, who was fatally gunned down near a Chicago Lawn gas station, is pleading for witnesses to come forward.

Cole was shot 24 times while he was heading to the gas station at Western Avenue and Marquette Road Saturday evening for snacks.

His aunt, Brandy Martin spoke with WGN News on Sunday, revealing that she has lost her sister and daughter within the last three years. She says she is still in shock three days after the murder of her nephew.

“Sincere was creative, ambitious. An entrepreneur at 15. He found a way,” Martin said. “Standing at the gas station pumping people’s gas to make money; it’s better than knocking an old lady in the head for her purse. He didn’t have to die.”

Speaking to reporters three days later, Martin revisited the site when Cole lost his life Saturday night.

“My nephew balled up and pleaded for his life,” Martin said. “Somebody say something.”

Overcome with grief, loved ones of Cole are pleading with the public to help in their pursuit of justice.

“Someone seen something. Please speak out,” Martin said. “Don’t wait for it to happen to you, and you have to stand in front of these cameras and ask for the same help you refuse to give.”

Martin is hoping surveillance video from stores and apartments nearby can help solve the crime.
