LIMA, Peru - Angry Peruvian onlookers shouted "Disgrace!" and "Murderer!" at Joran van der Sloot on Friday after a judge ordered him jailed on first-degree murder and robbery charges in the killing of a 21-year-old Lima woman.

Prosecutors said the Dutchman, who was taken to a segregated block of an eastern Lima prison, acted with "ferocity and great cruelty" in killing business student Stephany Flores in his hotel room after they met playing poker.

Van der Sloot remains the lone suspect in the 2005 disappearance of U.S. teen Natalee Holloway on the Caribbean resort island of Aruba, and Peru's criminal police chief says the defendant told interrogators he knows where her body is.

Aruba's attorney general, Taco Stein, said on Friday he was skeptical van der Sloot was telling the truth about Holloway's body. He said Aruban officials would decide whether to send investigators to Peru to question him once they learn exactly what he is offering. - AP

CIUDAD JUAREZ, Mexico - At least 30 gunmen burst into a drug-rehabilitation center in a Mexican border-state capital and opened fire, killing 19 men and wounding four people, police said. Gunmen also killed 20 people in another drug-plagued northern city.

The bullet-riddled bodies of 18 men and two women were found Friday in five parts of Ciudad Madero, a city in the northeastern state of Tamaulipas, where violence has surged this year amid a turf battle between the Gulf cartel and its former ally, the Zetas gang of hit men. Another round of killings occurred late Thursday at the Faith and Life center in Chihuahua city, about 210 miles south of Ciudad Juarez and the border with El Paso, Texas, state police spokesman Fidel Banuelos said.

The killings marked one of the bloodiest weeks ever in Mexico and came just weeks after authorities discovered 55 bodies in an abandoned silver mine, presumably victims of the country's drug violence. - AP
