The drummer of the alternative rock group Foo Fighters, Taylor Hawkins, had consumed cannabis, opiates and antidepressants before dying on Friday night in a hotel in Bogota, the Colombian prosecutor's office announced on Saturday.
"The toxicological analysis reports ten substances so far found in Taylor Hawkins' body, including THC (cannabis), antidepressants, benzodiazepines and opiates," prosecutors said in a statement.
Medical examiners continue to work "to fully clarify the facts leading to the death" of Hawkins, he added.
"Chest Pain"
Shortly before dying, the 50-year-old drummer complained of "chest pain".
Called for help at his hotel, a general practitioner tried unsuccessfully to resuscitate him, according to the town hall of Bogota.
The Foo Fighters, one of the most notorious alternative rock bands on the American scene, often acclaimed by critics, winner of several Grammy Awards and author of big hits, were to play this Friday in Bogota on the occasion of the Estéreo Festival Picnic.

Tributes poured in from the music world, with the legendary Ozzy Osbourne hailing him as "a great person and an incredible musician", and punk rocker Billy Idol calling the news "tragic".
Rage Against The Machine guitarist Tom Morello praised the deceased's "unstoppable rock power".
"Totally in disbelief at the news of Taylor Hawkins' death," rock band Nickelback tweeted.
In an interview given to Californian radio 95.5 KLOS last year, Dave Grohl recounted his first meeting with Hawkins.
“I said, 'well, you're my twin or my spirit animal, or my best friend', and we've only known each other for ten seconds!
“And of course I had seen him play drums and I thought he was an amazing drummer,” he added.
"When I called him and said , '
Listen, I'm looking for a drummer,
he said,
'You know I'm your man.
I think it had more to do with our personal relationship than something musical,” the ex-Nirvana drummer said.
