From Inside Edition.

A summer afternoon turned into a nightmare for two brothers. Fifteen-year-old Duke Brimhall was wakeboarding as his older brother left the wheel to hand him a soda but slipped. The 21-year-old Bo fell into the Montana lake, leaving the runaway boat pulling Duke. As Duke tried to pull himself into the boat, a wave hit and he also fell into the water. Both brothers watched as their boat powered on without anyone at the wheel. Luckily, two jet skiers saw everything and came to the rescue.
