LIMA, June 7 (UPI) -- Security surrounding Dutch homicide suspect Joran van der Sloot tightened after prison guards learned of a possible suicide attempt, Peruvian officials said.
Van der Sloot, 22, is charged in Lima with killing Stephany Flores Ramirez, 21, whose body was found in his hotel room last week. He also is a suspect in the 2005 disappearance and possible homicide of Natalee Holloway of Alabama who vanished while on a high school graduation trip to Aruba. He was captured in Chile and returned to Peru last week.
