The Essex County Coroner's Office released its report Monday on the singer, who was found dead one week ago.
The report confirms what Flint's bandmates said shortly after news broke he had died.
Prodigy founder Liam Howlett said Keith had taken his own life, leaving him, "shell shocked, f**kin angry, confused and heart broken." The coroner is still completing toxicology testing, but is confirming there was no foul play involved in Keith's death.
The singer was found in his home when a concerned friend asked police to make a welfare check.
He was 49.
