Re-enactment, formal charges in store for van der Sloot in Peru slaying

Lima, Peru (CNN) -- Joran van der Sloot, the longtime suspect in the disappearance of Alabama teen Natalee Holloway, could be formally charged as early as Wednesday in the death of a Peruvian woman, authorities said.

Also Wednesday, van der Sloot is expected to re-enact for investigators the crime in his room at Hotel Tac, said Peru National Police Col. Abel Gamarra.

That re-enactment was originally slated for Tuesday but was delayed for security reasons.

Stephany Flores Ramirez' body was found in van der Sloot's hotel room last week. The 21-year-old woman was killed after she discovered information on his laptop linking him to Holloway's disappearance, a source with direct knowledge of the investigation told CNN.

Van der Sloot was interrogated for seven hours Monday, the source said.

The Dutch citizen told investigators that he left the hotel room to buy bread and coffee at a gas station next to the hotel, the source said
