“The doctors are saying that it doesn’t look good,” said Melody Hatampa, the child’s grandmother. “He’s on life support. He’s … um … no brain activity.”

JR’s mother is searching for strength and answers.

“My baby was so small and to see him fly a hundred feet and not even stop …” said Angel Montes, the child’s mother.

The family says JR was playing at the end of the driveway when he saw his uncle across the street. He ran into the street, and that’s when he was hit.

The crash Tuesday happened about 6 p.m. Tuesday.

Investigators say it’s likely the driver was going 40 mph in a 25 mph zone. JR’s uncle heard the impact and watched the driver speed off.

“The car didn’t even slow down. You didn’t even hear a screech. The car just kept going,” said Nicholas Ortega, JR’s uncle.

JR is being treated at Loma Linda University Medical Center.

“Even if he does make it, he’s not going to be the same, but gosh, we’re going to miss him,” JR’s mother said.
