Newly released surveillance video shows the moments before a man walking his dog was hit and left for dead in Little Havana.

The incident happened around 9:45 p.m. Saturday at the intersection of Northwest 12th Avenue and 4th Street. Witnesses told police the victim, 24-year-old Pedro David Gonzalez, was attempting to cross Northwest 12th Avenue from east to west, when he was hit by a vehicle.

Officials said the driver of that vehicle got out of the car and looked at Gonzalez on the ground before he continued driving southbound.

Family members said they knew something was wrong when Gonzalez's dog returned to the home without his owner, and even rode an elevator alone to the family's apartment.

Gonzalez was taken to Jackson Memorial Hospital's Ryder Trauma Center, where he underwent surgery. He remained in critical condition through Sunday, but was pronounced dead in the late afternoon.

Police were looking for a green 2006 Chrysler 300 with extensive front-end damage, in connection with the crash. The vehicle was located on Monday in the 3000 block of Northwest 11th Street in Miami. The driver is still wanted.

Carmen Montoya, Gonzalez's mother, said she feels she has a little more closure now that police found the car involved, "I knew that if they found the car, they're going to find the person."

"We want to know a lot more. We want to know who it belongs to, who was behind the wheel, and why the driver fled," said Kenia Fallat with Miami Police.

A car part that was left on the scene is how police zeroed in on the make and model of the vehicle.

Montoya said once she learns who is responsible for her son's death, she plans to seek justice, not revenge, "I do believe the person needs to pay, in all fairness, because we are responsible for our actions."

Anyone with information is asked to call Miami-Dade Crime Stoppers at (305) 471-TIPS. The driver could potentially face charges of leaving the scene of a crash involving death, and failure to render aid.
