WORLD EXCLUSIVE: Witness Who Found Murdered Woman In Joran Van Der Sloot's Room; Read Her Witness Statement

Inadvertently, it was a telephone call for van der Sloot from a mystery woman who sparked a search for the 22-year-old Dutchman, she said.

"I transferred the call to this room," Adeli recounted to police investigators in her native Spanish.

"Since nobody answered, I told the woman he must be resting because his key was not at the front desk -- and I hang off the phone."

Adeli said she then realized van der Sloot was behind on his room payments.

She added, "So I went up to his room to knock the door and insisted several times, because I could hear the television or radio volume high.

"I listened outside of the room and thought that Mr. Joran must have been resting.

"I went back to the front desk and communicated this to the manager, Iris, who told me to go upstairs again with a key to open the room.

"I went and opened the door... and when I walked in I noticed the room’s light was on, the television had regular volume, there was a pair fabric slippers, the bed was a mess, all the bed-cloths and a pile of clothes were on the floor.

"I turned my head right and I saw a person in the floor, which scared me and at first, I thought it was Joran."

At that point, Adeli admitted fear was running through her mind.

"I approached and I observed that the person had long hair," she told Peru's homicide squad.

"As I got closer, I realized it was a dead woman -- and her nose was bleeding, she was dressed in a dark t-shirt and red underwear.

"She was covered with a white sheet, but I did not manage to see anything else, because I panicked."

With that, Adeli said she hastily turned off the television and the room’s light and "left the room running" to raise the alarm to the hotel manager.

Shocked at the bloody discovery, Adeli rang her husband, who a short time later, showed up to comfort her.

The witness statement also provides a window into van der Sloot's life in the weeks before the brutal murder.

She said he first checked into the hotel on May 14, 2010.

Police asked Adeli to recall the last time she saw van der Sloot, who is also the prime suspect in the murder of American teenager Natalee Holloway, who vanished in Aruba back in 2005.

In a chance and chilling confrontation just moments after the murder, the hotel worker revealed she passed van der Sloot in the street outside the hotel, completely unaware to what had occurred earlier.

Adeli said, "I passed him... he was carrying in both hands two cups of coffee and chocolate, which he had apparently bought at the the store next to the hotel."
