Taylor Hawkins had a cocktail of drugs in his system at the time of his death.
Per Colombia's Attorney General's office, medical examiners in Bogota were said to have found traces of at least ten different illicit substances in the rocker's body.
"Colombia’s National State Prosecution Service can confirm the following after the initial autopsy on the body of Taylor Hawkins," the statement read. "That in the toxicology test on Taylor Hawkins’ urine ten types of substances were preliminarily found, including marijuana, tricyclic antidepressants, benzodiazepines, and opioids."
The autopsy also revealed the Foo Fighters drummer's heart was significantly enlarged — likely due to strain from drug use — weighing "at least 600 grams", double the average size for a 50-year-old man, which then resulted in "cardiovascular collapse."
"The National Institute of Forensic Medicine is continuing its medical studies to be able to completely clarify the facts that led to Taylor Hawkins death," the statement on the rocker's tragic passing continued. "Colombia’s National State Prosecution Service will continue with its investigation and reveal the results obtained as part of this investigation as appropriate."
As OK! previously reported, Hawkins was found dead in his hotel room after telling hotel staff he had been suffering from chest pains. Although medical services were called, the rocker had passed away by the time they arrived.
The band announced Hawkins' passing in a heartfelt tribute shared on Twitter on Friday, March 25.
"The Foo Fighters family is devastated by the tragic and untimely loss of our beloved Taylor Hawkins," they wrote to fans. "His musical spirit and infectious laughter will live on with all of us forever."
The band have since cancelled all upcoming concerts.
