Investigators believe two cars may have been racing at the time.
Video taken by a neighbor shows the moments after police say one of the cars crashed into a light pole at Hillsdale and Meridian avenues.
Both drivers left the scene.
Friends of the victim, who was a passenger in one of the cars, gathered on Saturday night to light candles and reflect on their loss.
"He was smart, he had a lot going for him," said friend Matthew Paz. "He could've been a mechanic, an engineer."
Two other teenagers went to the hospital with serious injuries.
Police say alcohol was a factor in the crash.
