A family spokesman said Senna’s family may sue auto racing authorities for last weekend’s death of the three-time Formula One champion. Senna, 34, died of multiple head injuries when his Williams-Renault car slammed into a concrete wall at nearly 180 mph at the San Marino Grand Prix in Imola, Italy. (AP Photo/Ignacio Teixeira)
