It was a celebration of life at Gibson Park for Malcolm Nicholas III.

The 19-year-old basketball standout, set to pick a college, was shot and killed Sunday on an Overtown Street.

“He had a lot of friends. I’m pretty sure that he was with someone when this happened to him that night and right now my family just wants justice,” said Tia Kemp, the teen’s aunt.

Nicholas III, back in town from a Tennessee basketball academy, wasn’t supposed to be in Miami until the week of Thanksgiving. He was shot while walking home after visiting his grandmother.

“He was just a joker, witty kid, you know, a happy, happy little boy,” Kemp said. “He was definitely destined for greatness. He had a bright future ahead of him.”

The 19-year-old’s father – Malcom Nicholas Jr. – is a former Miami Senior High School basketball player and mentor to Miami Heat captain Udonis Haslem.

The grieving Miami Heat player posted a video on Instagram and wrote a heartfelt message.

Nicholas III’s mother, who was not ready to speak on camera, told CBS Miami she don’t understand what happened.

“I want my baby back,” she said, crying.

Police have no leads, no witnesses.

“Right now we need some answers to why this happened to him and we just need this person off the streets because it could be your brother, he could be your son,” Kemp said.
