Joran van der Sloot: Stephany Flores Ramirez Murder (PHOTOS, VIDEO)

Joran van der Sloot, 22, the Dutch man arrested and later released in the May 30, 2005 disappearance of Natalee Holloway, is now suspected of killing Stephany Flores Ramirez in Peru on May 30, 2010 — exactly five years, to the day, after the first crime was committed in Aruba.

At a news conference held in Lima, Cesar Guardia Vasquez told the gathered reporters there is “incriminating evidence” linking van der Sloot to the killing of the 21-year-old woman. Her lifeless body was discovered face down in his hotel room – with multiple stab wounds.

Several witnesses saw the couple return to his room at 5:00 a.m. on Sunday. Video from the previous night shows the pair at the Atlantic City Casino in Lima. The woman’s father, Ricardo Flores, told reporters that his daughter’s car was found 50 blocks from the hotel, and inside they found date rape drugs. It is believed to be the vehicle used by van der Sloot to flee the murder scene at the hotel.

According to immigration officials, van der Sloot crossed into Chile on Monday and may be headed for Argentina. Interpol has issued an international arrest warrant.
