Killed on Sunday, Takesha Hayes’s family is demanding justice, asking the driver responsible to come forward.

Hayes, whose daughters are 6 and 17-years-old, had cerebral palsy and used a motorized wheelchair.

Her family said she was coming home from the store a few blocks from her home at 2:30 Sunday morning when she was hit.

Hayes younger sister, Kenya Broomfield, has been trying to help Hayes daughters come to terms with the loss of their mother.

“My sister was 39-years-old. She wouldn’t hurt a fly. I love her with all my heart,” said Broomfield.

“For them to just leave her there like that and just keep going—that’s a person with no heart,” said Broomfield.

Hayes family said the driver hit her on NW 54th Street, and then dragged her body which ended up a block and a half away.

“If they were a real person they would’ve stopped to make sure my sister’s OK and make sure they get her help immediately,” Broomfield said.

The hit and fun has left a lasting mark on Hayes’s family, one that only can be partially soothed by an arrest.

“We’re grieving and I just wish my sister was here and the person that did this—I just want them brought to justice,” said Broomfield.

The SUV captured on surveillance is a 2011-2014 dark Ford Explorer. Anyone with information is urged to call Crime Stoppers at 305-471-TIPS.

“Somebody knows something. Just come forward. You’re making it worse. They’re gonna catch you and when they do I hope they give you the stiffest penalty possible,” said Kevin Wimbley, Hayes brother-in-law.
