SANTA ANA, Calif. - A former Marine already accused of killing four homeless men was charged Monday with two new counts of murder in the stabbing deaths of his high school friend's mother and older brother.

Charges were dropped Friday against Estrada's son Eder Herrera, 24, a former schoolmate of Ocampo.

Orange County District Attorney Tony Rackauckas said Ocampo didn't only prey on the homeless.

MADRID - Alberto Contador was stripped of his 2010 Tour de France title Monday and banned for two years after sports' highest court found the Spanish cyclist guilty of doping.

The Court of Arbitration for Sport suspended the three-time Tour champion after rejecting his claim that his positive test for clenbuterol was caused by eating contaminated meat on a 2010 Tour rest day.

The three-man CAS panel upheld appeals by the International Cycling Union and World Anti-Doping Agency, which challenged a Spanish cycling tribunal's decision last year to exonerate Contador.
