“Come forward, just come forward,” said Khaliff Williams, Markalyah’s father. “It’s very overwhelming. I just can’t speak right now. I’m at a loss for words. I just want the person who hit my daughter to come forward.”

Police said Markalyah did everything right, crossing Adams Avenue at the crosswalk and with the signal. But the vehicle turning from Roosevelt Blvd, also had a green light, and struck her and didn’t stop.

“She was sent through the air about 160 feet, somewhere, which indicates that she was hit at a fairly high rate of speed,” said Capt. John Wilczynski of the Accident Investigation District.
