According to the BBC, THE PRODIGY singer Keith Flint had unspecified amounts of cocaine, alcohol and codeine in his system when he died two months ago.
The Senior Coroner for Essex, Caroline Beasley-Murray, officially recorded an open conclusion, saying that there was not enough evidence to rule that the musician killed himself.
Flint was found dead at his home in North End, Essex, on March 4. The 49-year-old had died due to hanging.
Beasley-Murray said: "We will never quite know what was going on in his mind on that date.
"I've considered suicide. To record that, I would have to have found that, on the balance of probabilities, Mr Flint formed the idea and took a deliberate action knowing it would result in his death.
"Having regard to all the circumstances, I don't find that there's enough evidence for that."
The coroner also said there was insufficient evidence to record the singer's death as an accident where he may have been "larking around and it all went horribly wrong."
THE PRODIGY was scheduled to embark on a U.S. tour in May. The 10-date trek was slated to include appearances at several festivals, including Sonic Temple in Ohio and Welcome To Rockville in Florida.
Originally recruited mainly as a dancer for THE PRODIGY, Flint became the voice and face of the group for its 1997 third album, "The Fat Of The Land". The breakout LP produced the hits "Breathe", "Firestarter" and the controversial "Smack My Bitch Up", reaching No. 1on the Billboard 200 in July 1997.
Flint's cartoonishly demonic look, punk attitude and frantic dance moves became the visual trademark of THE PRODIGY, one of the first electronic dance music acts to become a mainstream success. But Flint's role in the band was reduced after the release of another controversial track, "Baby's Got A Temper", in which Flint celebrated the "date rape" drug Rohypnol.
The singer/dancer did not appear on "The Fat Of The Land"'s 2004 follow-up "Always Outnumbered, Never Outgunned", which featured guest vocalists in his place. He returned for 2009's "Invaders Must Die", and contributed both vocals and songwriting to 2015's "The Day Is My Enemy" and THE PRODIGY's most recent LP, 2018's "No Tourists".
In 2006, Keith married Japanese DJ, actress and model Mayumi Kai, but the couple reportedly separated three years ago.
He previously admitted to a long battle with drink, drugs and depression and said his wife "saved him."
