The woman who Joran van der Sloot is accused of killing had drugs in her system at the time of her death, according to the official toxicology report obtained exclusively by RadarOnline.com.
The report reveals that amphetamines were found in the body of Stephany Flores Ramirez. It is not known if she took the drugs voluntarily or if van der Sloot gave them to her or had her ingest them unknowingly.
The report is in Spanish.
Van der Sloot confessed to killing Flores Ramirez, 21, in a Lima hotel room after the two met playing poker at a local casino. He has since recanted his confession.
The toxicology report, obtained exclusively by RadarOnline.com from sources close to the investigation, also revealed that cocaine and alcohol were not detected in Flores Ramirez' system at the time of death.
It states, "The analysis gave positive only to amphetamines."
The document poses new questions for homicide detectives probing the brutal May 30 murder.
Van der Sloot allegedly said he slammed her in the face with his right elbow, strangled her for a full minute and then suffocated her with his clothing. He later recanted that.

The long-time suspect in the disappearance of Natalee Holloway reportedly admitted he popped three amphetamine pills as he considered what to do with Flores Ramirez' dead body.
He also reportedly told investigators he was high on marijuana when it all happened.
Video from hotel security cameras shows Flores Ramirez and van der Sloot entering his room together at 5 a.m. -- and then shows the 22-year-old leaving alone four hours later with his bags.
"I was going to use one of the traveling bags to take the body out of the hotel," Van der Sloot told police in the disputed confession.
"I didn't because I was afraid to be confronted because I was leaving without paying."
Flores Ramirez was found dead in the hotel room three days later, on June 2, setting off a police manhunt that ended with his arrest in Chile the following day.
