The boy was buckled in the Acura Integra when the car plunged into the river.
Patrick McClain witnessed the incident. "I just heard this noise, turned around. Saw this car upside down going into the water."
McClain called police, another witness flagged down Nate Durbin who was jogging. The former wildwood lifeguard and another unidentified man jumped into the 13-feet deep water.
"It's murky, we couldn't see what was going on, it was free for all. The car was red so you could make that out," said Durbin.
For more than 5 minutes the two men took turns going under, trying to free the boy. Finally, one of the men pulled the car door open and was able to pull the child out.
The boy was rushed to St. Christopher's Hospital where he's in critical condition.
Investigators are still trying to figure out how the car got into the water, according to police. The boy's mother says she was putting picnic gear in the trunk when the car began to roll.
