Detroit police are searching for a driver who struck a grandmother and her granddaughter on the city's west side Thursday evening.
The grandmother -- who was using a walker while crossing the road -- did not survive her injuries.
The suspect is believed to be driving a black truck.
Toashia Hardy tells 7 Action News that her 53-year-old mother Vanessa Larkins was going to the store with her 15-year-old granddaughter when a speeding driver struck them in order to run a red light.
It happened at the intersection of West Warren and Penrod on the west side at about 6:30 pm.
"By the time I got here, she was rolling my mother over. She was unconscious, but breathing. My daughter is sore, too. My mother took most of the impact" says Hardy.
Detroit police are asking for the public's help with this case, and reviewing possible surveillance video from the scene.
"Cars speed up Warren and my mother is in a walker. Why are you speeding towards them?" says Hardy.
Toashia hopes her daughter will be released from the hospital soon.
So far, no detailed description of that truck has been released.
Anyone with info is urged to call Detroit police right away.
