A Henry Ford doctor who stopped to help crash victims and was struck by a second vehicle on a Detroit highway Sunday has died of her injuries.

Dr. Cynthia Ray, 47, who worked at Henry Ford Hospital, was hit by a second vehicle after she exited to help six passengers in a Jeep that lost control and collided with the median on eastbound Interstate 96 near the Davison Freeway about 7:50 a.m. Sunday, state police said.

"Our hearts are heavy today after the passing of Dr. Cynthia Ray," the hospital posted on Twitter Thursday morning. "Our prayers are with The Ray family and the Henry Ford staff who knew her."

Seventeen-year-old Sean English, a Detroit Jesuit High School junior, also exited his vehicle to help with the crash and was hit but is expected to survive.

English, who competed in track and field, lost his foot and police credit Trooper Patrick Arena, who fashioned a tourniquet to stop the bleeding, with possibly saving his life.

"Several motorists (Good Samaritan's) stopped to assist the occupants in the Jeep and were out on foot when a second vehicle also traveling eastbound lost control," police said. "It appears the second vehicle spun out striking the pedestrians who were out of the vehicle at the time of impact."

State police said they are investigating the crash and haven't announced the issuance of any citations or criminal charges.
