A Stamford teenager is now charged with negligent homicide with a motor vehicle and evading responsibility for a deadly crash involving a scooter four months ago.

On May 29, just before 11 p.m., Stamford police responded to the area of 100 Hope St. near Howes Avenue after a 911 call from neighbors reported a crash involving a car and a scooter, according to Sgt. Jeffrey Booth.

Booth said when police arrived, they found the scooter rider, 46-year-old Christian Dinamarca, of Stamford, lying in the street with the scooter in pieces.

“He was, at that point, awake and able to communicate. He really didn't know what happened because he got hit pretty hard, and then a couple people came out—witnesses—and told us they just heard a crash,” Booth stated.

But there was no sign of the car involved, according to Booth.

“Later that night, not long after the crash, we did find the operator had walked back to the scene,” Booth told News 12, adding that the driver was just 17. “We found the vehicle eventually. We did find significant damage to the windshield and the front of the vehicle which would indicate a pretty decent impact.”

Booth said Dinamarca went to the hospital with life-threatening injuries and died on June 11. The investigation determined he wasn't at fault.

“The scooter operator, we believe, was going home. He lived north of that area. He was traveling northbound somewhere near the side of the roadway. It appears that the vehicle somehow probably veered out of the travel lane and struck him from behind, and then left the scene,” Booth explained. P

Police obtained an arrest warrant for the driver, who turned himself in over the weekend. He posted a $100,000 surety bond and will be arraigned at Stamford Superior Court next month. Booth said police are not identifying the driver because he’s under 18.

“There appears to be increasing scooter-related crashes. There are a lot more of these types of vehicles on the roadway—a lot more electric bicycles, a lot more scooters, things like that,” Booth told News 12. “I would just caution everyone—just watch out for each other. Please pay attention while you're driving.”
