Authorities have identified an Alberta skydiver who died Monday afternoon when he fell onto the roof of a home in Southern California.

The Riverside County coroner's bureau says the victim was Aime-Jean St. Hilaire-Adam, a 27-year-old from Calgary.

Friends said St. Hilaire-Adam, who was originally from Quebec, was taking part in a skydiving competition at the time. 

He fell onto a home in the 200 block of Caldera Street in Perris, about 112 kilometres southeast of Los Angeles.

The home is about three kilometres southwest of Perris Valley Airport, which is a popular spot for skydivers.
