The body of Vunies High, who had Alzheimer's disease, was found Monday outside The Heatherwood retirement complex in Southfield, a Detroit suburb, said Capt. Tom Colombo of Southfield emergency medical services.
High, who spent 25 years as a teacher and counselor for Detroit Public Schools, was last seen Sunday. When she was found, she was dressed only in pajamas and was wearing one shoe, with the other lying nearby. An autopsy shows she died of hypothermia.
An official at Swanson's Funeral Home in Detroit confirmed that High was Louis' sister. A message seeking comment was left Wednesday at The Heatherwood.
Southfield police said Wednesday night they had no information on the death or whether it was under investigation.
Louis, who transcended racial divisions 1930s and 1940s, remains a local hero in heavily black Detroit, where he grew up. The arena where the NHL's Detroit Red Wings play bears his name, and one of the city's most famous landmarks - a bronze sculpture of an arm and fist - is dedicated to his memory.
