Daunting journey for resilient 'Missing Kidney'

Isaquias Queiroz was badly scalded at age 3, was kidnapped two years later and at age 10 he lost a kidney after falling from a tree.

To say he's had a rough start in life is an understatement.

The 22-year-old became Brazil's first medalist in flatwater canoeing on Tuesday, winning a silver in the 1,000m singles. He's also competing in the 200m sprint and the 1,000m doubles.
