HOBOKEN, N.J. (CBSNewYork) — Police in Hoboken are investigating a deadly hit-and-run that claimed the life of a young man related to an NBA star.

Zachary Simmons, 21, of Ramsey, was struck and killed by a black SUV around 3:30 a.m. Saturday at Willow Avenue and Sixth Street.

The impact was so great witnesses reported hearing two loud thuds.

The victim’s grieving mother, Monique Steele, told CBS2’s Steve Langford that police told her the car was going at least 70 miles an hour.

“To be speeding enough to kill my child is beyond me,” Steele said.

The young victim was out for a friend’s birthday Friday evening, after celebrating his cousin Ben Simmons’ selection this week by the Philadelphia 76ers, his mother said.

“He had just went to the NBA draft for his first cousin — number one draft pick” Steele said.

Ben Simmons wrote on Twitter, “I’m glad I could share this moment in my life with you. Rest in peace Cuzzo.”

Police are looking for a black Cadillac Escalade, Yukon, or Tahoe which may have New York plates.

Neighbors are shaken by the incident.

“I can’t believe that. Who would do that?”

Some suggest the city install four-way stops at the intersection

“This area sometimes has issues with people driving quickly on streets they’re not supposed to I guess they’re coming from the bars,” Hoboken resident Maguel Villalobos said.

Meanwhile, investigators are analyzing pieces of the SUV and checking surveillance video.
