According to CBS New York, Steele said Zachary Simmons was out Friday evening celebrating a friend's birthday. The day prior, he was in New York with Ben Simmons to hear his name called at the Barclays Center.

"He had just went to the NBA draft for his first cousin—No. 1 draft pick," Steele said, per CBS New York.

No suspects have been named, but CBS New York reported that "police are looking for a black Cadillac Escalade, Yukon or Tahoe, which may have New York plates."
