Members of the Ochapowace First Nation are mourning the loss of their longtime chief, Denton George, who died Sunday at the age of 58.

It was reported Monday that George may have died of a heart attack. He had served his community as chief for the last 20 years.

The main reserve is located about 200 kilometres southeast of Regina.

George was well known for developing a ski hill operated by the band. He also led a protracted legal battle against the government over the collection of the federal sales tax, the GST, on reserve. However, the courts sided with government authorities.

George is survived by his wife, two grown sons and a number of grandchildren.

A wake has been scheduled for Wednesday evening on the reserve. A funeral will take place Thursday afternoon in the Ochapowace school gymnasium.
