According to The Guardian, Maxwell's death was officially ruled to have been caused by a heart attack combined with accidental drowning.
However, Maxwell's cause of death also became the subject of many conspiracy theories, INSIDER previously reported. His death had been widely speculated by the public to be a suicide because it occurred during a period of financial turbulence for his company.
Years after his father's death, one of Maxwell's sons spoke out against the suicide theories.
"In 27 years I've never speculated: was he killed or did he kill himself?" Maxwell's son Ian told the Sunday Times 27 years after his father's death, according to The Guardian. "If I say anything about it, I think it is highly unlikely that he would have taken his own life, it wasn't in his makeup or mentality. I don't think any murder conspiracy stands up, so for me, it is an unexplained accident and I'm content to live with that."
Maxwell's companies owed more than $4 billion to 43 different banks at the time of his death, according to the Daily Beast.
After her father's death, Ghislaine Maxwell moved to the Manhattan's Upper East Side and began working in real estate. According to a New York Post article from 2000, she was living off about $100,000 a year from a trust fund her father had set up.
