A Cedar Hill family is asking a man suspected of critically injured a 7-year-old girl in a hit-and-run crash to turn himself in.
Seven-year-old Timiyah Miles was struck Sunday while walking on the sidewalk with a family friend on East Grauwyler Road in Irving.
Police said 27-year-old Marvin Perez was driving eastbound on Grauwyler Road when he inexplicably crossed the center median, jumped a curb and crashed his green Mazda 626 into Timiyah and the family friend.
Investigators said Perez sped away in his car before ditching the vehicle and running as witnesses pursued him.
"It could be your daughter," said Cecelia Miles, the child's grandmother. "Just put yourself in our shoes for a few moments and look inside your heart and realize you have to turn yourself in."
Timiyah has a critical head injury and is in a medically induced coma.
"It's not right our little girl is lying in a bed right now fighting for her life," Miles said.
The family friend who was with Timiyah is in critical condition at a Dallas hospital.
Police said they hope to make an arrest soon.
"We need to know that he will not do this to anybody else," said Regina Allen, Timiyah's aunt.
Irving police are asking anyone with information about Perez to call investigators at 972-273-1010.
"We believe in God for a miracle, and that's what it's going to take -- a miracle," Miles said.
If Timiyah recovers, she will need significant therapy. The Miles family has started a medical care fund for her at Wells Fargo bank.
