It was Christmas Eve in 1967. William Lynn Weaver, 18 at the time, was walking in Mechanicsville, the neighborhood he grew up in in Knoxville, Tenn., when he saw a boy gliding down the street on a bicycle.
"Boy, that looks like my brother's bike," he mused.
When he got home, he asked his younger brother Wayne where that bicycle was. "It was down on the steps," he replied. But it wasn't.
The Weaver brothers tracked down where the boy lived — an unlit shack in an alley — and planned to confront him.
