Boat explosion on Beaver Lake kills one

A woman was killed in an explosion on a boat Friday afternoon on Beaver Lake.
The Benton County Sheriff's Office said Kayla Woolsey, 23, of Missouri, was boating with her step-father, Alan Bland, on Beaver lake.
Bland docked the boat and was trying to do some welding repair work when the explosion happened.
Woolsey was thrown from the boat.
Deputies said there were oxygen tanks on board but are not sure if they contributed to the explosion.
