A tight-knit community of snowbirds in Florida was in mourning Tuesday after three elderly women -- two of them Canadians -- were killed in what appeared to be a horrific freak accident.

Residents of the mobile home community of Bradenton were leaving a Sunday church service at the Sugar Creek Country Club when a 79-year-old woman driving an SUV backed into a group of seven people at high speed.

Seventy-two-year-old Margaret Vanderlaan and 70-year-old Wilhemina Paul, both from Ontario, and 80-year-old Johanna Dijkhoff, who was visiting her Canadian sister from the Netherlands, were killed.
