Liam Payne's BAC Levels Exposed

Four months after his death, authorities have revealed the details of Liam Payne's toxicology report, showing that the singer had a blood alcohol level (BAC) of .27 percent at the time of his passing.

Payne, a member of the boy band One Direction, fatally fell from his hotel balcony in Argentina on October 16 at age 31. According to the National Criminal and Correctional Prosecutor's Office, the singer's BAC was more than three times the United States' legal driving limit, which is .08 percent.

"This situation would also rule out the possibility of a conscious or voluntary act on the part of the victim," Argentina's public prosecutor said in a statement. "since, in the state he was in, he did not know what he was doing nor could he understand it."

A blood alcohol level that high would be classified as “severe intoxication,” according to Stanford University’s Vaden Health Services, which states that people under such an influence may need help walking, may experience mental confusion and could have nausea or vomiting.

Three months before the details of Payne's toxicology report were shared, an initial test indicated that alcohol, cocaine and a prescription antidepressant were in his system when he died—though the exact amounts were not disclosed. Officials also concluded that Liam was likely not fully conscious at the time of his passing because they found no signs of self-defense.

Considering all the information gathered from the investigation, authorities also confirmed that the 25 injuries he had sustained were consistent with a fall from the height of the balcony. "The head injuries were sufficient to cause death," the prosecutors’ statement added, "while the internal and external hemorrhages in the skull, thorax, abdomen and limbs contributed to the mechanism of death."
