NEW YORK (CBSNewYork) — Police have released surveillance video of a vehicle they believe was involved in the fatal hit-and-run of a bicyclist on the City Island Bridge on Friday night.

Gabriela Aguilar-Vallinos, 27, of the Bronx, was on her bike riding west over the bridge at around 11:45 p.m. when the driver of a white 2015 Hyundai Genesis hit her and left seconds later, police said.

Officers said when they arrived on the scene, Aguilar-Vallino was unconscious and unresponsive with severe head trauma. The bike was found mangled nearby.

She was pronounced dead at Jacobi Medical Center.

“It’s a really hard situation for the entire family. We are all very sad and very depressed,” said cousin Lenin Ramirez.

Ramirez told CBS2’s Mark Morgan that Aguilar-Vallino came to New York from Mexico at 16 years old and live with him and his wife for the last 11 years.

“Gabriella, she was really, really energetic person. She was always positive in life. She had so many plans,” Ramirez said.

Co-workers at Sammy’s Shrimp Box on City Island are devastated. One of her co-workers said she rarely rode her bike to work at all.

“The fact that she was saving money to not take the bus and she took her bike, I think that was the third time that she took her bike and look at what happened; it’s devastating,” said co-worker Delyn Bernard.

General Manager Tommy Sinani said Aguilar-Vallino was a great worker.

“It was a pleasure working with her. We’re going to miss her dearly,” he said.

Police are asking for the public’s help in identifying and locating the driver of the Hyundia seen in the surveillance video.

The NYPD is urging anyone with information about the driver to call Crime Stoppers at 800-577-8477 or to submit a tip online at NYPDCrimeStoppers.com. All communications are kept confidential.
