The reason for dying of the infamous “Membership Youngsters” killer Michael Alig revealed

New details have become known about the convicted murderer Michael Aligis death.

E! In late December, the news confirmed that the former club sponsor, who served 17 years in prison, had died at the age of 54. Now the New York office of the Chief Medical Examiner has given more insight into Alig’s death, citing acute fentanyl, acetylfentanyl, heroin and methamphetamine poisoning as the cause of death. Alig’s manner of death was counted as an accident.

The New York Police Department previously announced that law enforcement officials responded to an 911 call on West 159th Street on Christmas Day that left Alig unconscious and unresponsive. According to the police report, EMS arrived shortly afterwards and pronounced Alig dead.

Alig made headlines for his infamous parties in the late 1990s and even co-founded the group of partygoers called “Club Kids” that became notorious on the NYC nightclub scene. In 1997, however, Alig was in the news for a different reason: the death of his drug dealer and friend Andre “Angel” Melendez. That year, Alig pleaded guilty to being involved in Melendez’s murder, according to Rolling Stone.
