"They must find this person, they must stop this person, because I don't want this to happen to another parent," said David Oyebola, the father of Oluwadurotimi "Timi" Oyebola.

Timi Oyebola was killed by a stray bullet Friday. His father said Tuesday that the killer took the life of a young man full of promise.

"Ambitious, focused, God-fearing," David Oyebola said inside his Queens home. "He's a teacher in the church, he's everything to me in the house."

Oyebola was also an A student, recognized by The National Society of High School Scholars. He had one passion: basketball.

The 16-year-old was shot while playing basketball with friends at the Chester Playground in Brownsville. Friends, community leaders, and faculty from his school gathered in the rain for a vigil Tuesday. Others remembered the teen through videos of him playing the game he loved.

"Any weather," said Andre Jean, a friend of the victim. "you would see him outside. It would be freezing cold, he would still have a bubble coat on with shorts, just playing ball."

"He was a competitor, he was always in school, he did what he had to do, he had his grades up and everything," another friend said at the vigil. "It really hurts that he's not here."

Oyebola remembers doctors telling him his son was dead on arrival at a local hospital. He now wonders if Timi could have been saved.

"Did he get help immediately? Did it — does it take time before they came?" the father asked. "How long did it take the police to get there? How long did it take the EMS to go there — to get there?"

Timi remembered now for his intelligence, generosity, and his love of Chris Paul and the Houston Rockets.

"If God asked me for another son today, I would still ask for Timi," David Oyebola said.

"Let them find out who did this," the father continued. "Our youth, they want an answer."

Oyebola said he also wants to talk to Mayor Bill de Blasio and other city leaders to push for more programs and services for children in Brownsville and in other parts of the city.

As of Tuesday night, police had not made any arrests in the case and the investigation was ongoing.
