June 15, 2010— -- After choking and beating Stephany Flores Ramirez in the face, a drunken Joran van der Sloot killed the young Peruvian by smothering her with his bloodied shirt so she would not be able to go to the police, the Dutch murder suspect told investigators, according to a transcript of his confession.

Calling the murder an "impulsive act," Van der Sloot gave a detailed description to Peruvian police about how he killed Flores, 21, in his Lima, Peru hotel room on May 30.

While the two played online poker on van der Sloot's computer, an instant message popped up alluding to the Dutchman's alleged involvement in the disappearance of American student Natalee Holloway.

Van der Sloot, 22, told police he received a message from an unknown person that read: "I'm going to kill you, you little Mongoloid."

When he explained that the message was a threat pertaining to his connection to Holloway's disappearance, Flores freaked out and lashed out at him, according to a transcript of his confession obtained by the Associated Press.

" She struck me on the left side of my head with her fist," he said.

"At that moment, impulsively, with my right elbow. I hit her in the face exactly on top of her nose," van der Sloot said, according to his confession

"I think she started to faint. It affected me so that I grabbed her from the neck and strangled her for a minute," he told investigators.

"There was blood everywhere. What am I going to do now? I had blood on my shirt. There was also blood on the bed, so I took off my shirt and put it on her face, pressing hard, until I killed Stephany," he said.

Police asked van der Sloot for a more detailed description of what happened, and he obliged with an even more graphic account of his assault on her.

"She was on the bed when I hit her hard with my right elbow and I think her head went back and hit the wall, then she begins to bleed. Immediately I get on top of her and with both hands I begin to strangle her, keeping her that way for a minute. After that, I throw her to the floor, but she keeps breathing. At that moment I take off my shirt and put it on her face, pressing on it. I don't remember for how long, but she stops breathing. In this way I think I caused her death," he said when investigators asked for a details description of the murder.
