Police in Saskatchewan are asking the public for help finding a missing boy whose mother was found dead on a beach.

Fort Qu’appelle RCMP said the body of Tamaine Geldenhuys, 47, was found Saturday at Echo Lake.

The cause of her death has not been made public.

Police said Sunday that they are seeking help locating Geldenhuys’ seven-year-old son, Greagan Geldenhuys. He is described as having blond hair and a slim build, and was last seen Saturday.

RCMP spokesperson Natalie Gray told The Canadian Press that three boats have been deployed to search for the boy in the waters of Echo and Mission lakes near Fort Qu'Appelle.

She would not say whether police think the boy may have gone into the water.

Anyone with information is asked to contact police or Crime Stoppers.
