A 15-year-old girl was badly injured last month after she was struck by a hit-and-run driver.

Piscataway police say that the crash happened Aug. 21 near the intersection of New Brunswick Avenue and Cedarwood Drive.

Tiffany Pham was walking through the intersection around 8:30 p.m. when she was struck. She suffered severe head trauma, a broken pelvis and other injuries.

Her twin sister says that they were excited to start their sophomore year together at South Plainfield High School. Instead, the family has stayed with the teen in her hospital room.

“We spend every day with her, praying with her. We read her stories, we make sure everybody we know is praying for her recovery,” says the teen’s older sister Ida Peery.

Police say that they do not have many leads. They say that due to Pham’s injuries, it would be impossible for the driver to not know that they hit her.

“We've checked video tapes from the area. We still have more to do just to get a speck of information that we can then move on,” says Piscataway Police Lt. Tom Mosier.

Pham’s family says that they want to driver to do the right thing and turn themselves in to police.

“Just feel kind of guilty for putting a little girl in a bed where she can’t move, she can’t talk, she can barely breathe,” Peery says.

Piscataway police are asking body shops to be on the lookout for any vehicles that may have front-end damage. Police says that there was a report of a dark-colored vehicle at the scene.
