Central Texas police say a 26-year-old woman has died of injuries suffered days earlier when she jumped from an elevated platform into a part of the Comal River where tubing is popular.
New Braunfels police say Kathryn Walker was pronounced dead early Thursday. An autopsy will be conducted by the Bexar County medical examiner's office.
The San Antonio Express-News reports Walker was on the river Saturday when she attempted a back flip into the water. The Austin woman dove to cheers from onlookers but failed to surface.
She was submerged for some 10 minutes in water up to eight feet deep before another swimmer found her. She was airlifted to a San Antonio hospital.
Police warned swimmers against jumping into the river without knowing what's under water.
