SALT LAKE CITY, Utah (AP) -- A Utah father says his teenage daughter and her friend survived a deadly boating accident after they swam for hours, singing songs and shouting prayers as they fought exhaustion. Jeff Stoker said Wednesday that his 13-year-old daughter Tiffany tried to swim for shore with her friend Tylinn Tilley after a violent windstorm capsized their boat, throwing all seven people aboard into the cold water. They were about to give up when they heard a rescue boat and started yelling.

The movement likely staved off the hypothermia that authorities say contributed to the deaths of four people: 46-year-old Utah doctor Lance Capener; his daughters, 13-year-old Kelsey Capener and 7-year-old Kilee Capener; and their friend, 13-year-old Siera Hadley. Forty-two-year-old Kathy Capener also survived.
