Authorities determined the former One Direction singer fell off his hotel balcony on Oct. 16 in a state of "semi or total unconsciousness." For the first time, the prosector's office said they have ruled out "self-harm of any kind" or that a third party was responsible for Payne's fall.

In the Nov. 7 statement, the prosector's office said a "detailed analysis of more than 800 hours of video footage" from security cameras helped lead them to the arrest of the three individuals.

One defendant who accompanied Payne "on a daily basis during his stay in the city of Buenos Aires" is charged with "the crimes of abandonment of a person followed by death."

A second person is a hotel employee "who must answer for two proven supplies of cocaine to Liam Payne" during the singer's stay at the CasaSur Palermo Hotel. The third deferent is "a narcotics supplier," the statement alleged, and that person is accused of selling drugs to Payne two different times on Oct. 14.

"Both were charged with the crime of supplying narcotics, two acts each," the statement read.

Prosecutors also revealed that toxicology tests confirmed Payne was under the influence of drugs "in the moments before his death" and for at least three days leading up to the incident. He had traces of alcohol, cocaine and a prescription antidepressant in his system.

Authorities say Payne "was not fully conscious or was experiencing a state of noticeable decrease or loss of consciousness at the time of the fall." Payne's cause of death was from "multiple trauma" and "internal and external hemorrhage" as a result of his third-story fall from the balcony of his hotel room.
