NW Miami-Dade, Fla. -

The mother of Neptalie Olivera, a young girl who lost her arm in a hit-and-run accident, spent her Saturday handing out flyers, desperate to find the driver who ran a stop sign and smashed into her family's car.

The suspect left the scene on Northwest 101st Street and 29th Avenue on Aug. 7 without ever stopping.

Henisse Carrera had many words for that driver. "Why didn't you stop to make sure we were okay," Carrera said. "Everybody could have lost their lives in the accident."

Olivera, 15, was the only one seriously injured out of six people in the car. She suffered severe trauma to her right arm, part of it had to be amputated.

"My daughter lost her arm, she just turned 15, now she has a disability," Her mother said. "She has to learn everything over again."

On Saturday, Olivera's mother got some help from the mother of Ashley Valdez, a 12-year-old who was hit and killed by a driver in January. Police arrested Harvey Abraham, 33, a week after Valdez was killed because of a tip from someone in the community.

Adonay Rosete said, "There's somebody out there that knows him, a friend, a relative, a body shop. Just make that anonymous call."

Anyone with information is being asked to call Miami-Dade Crimestoppers at 305-471-TIPS.
