Serena And Venus Williams' Father Is 'Incapacitated' After Suffering Two Strokes

Serena and Venus Williams' dad is 'incapacitated' after suffering from two strokes and the former hard-driving coach of the legendary tennis players is being cared for by a mystery son with a lengthy rap sheet.   

Richard Williams, 79, is barely able to speak and gave power of attorney not to his celebrated daughters but to Chavoita LeSane, a son he had through an unknown relationship, according to court records.
