It's been almost a year since Bobbi Kristina Brown passed away at the age of 22, and questions still remain about what caused her life to be cut so tragically short.
The toxicology and coroner's reports were unsealed in March of 2016, but the Atlanta Medical Examiner's office states that it was not "able to determine whether death was due to intentional or accidental causes."
Back in April, Bobbi Kristina's boyfriend, Nick Gordon, announced plans to publish a tell-all in which he would explain his various theories as to what may have killed the troubled 22-year-old.
Her father, Bobbi Brown, was reportedly infuriated by both the publication of the autopsy findings and Gordon's plans to "cash in" on Bobbi Kristina's passing.
The former New Edition singer subsequently announced plans to beat Gordon to the punch with his own memoir, which will reportedly hit stores next week.
Brown does not dismiss the theory that Gordon is to blame for Bobbi's death.
However, he also speculates that a car accident that occurred several days before she slipped into a coma may have played a role as well.
He writes, in a copy of the book obtained by Radar Online:
“We asked the doctors whether she could have suffered some type of brain trauma or hemorrhage that didn’t present itself until four days later, resulting in the bathtub incident."
“But the doctors couldn’t really give us definitive answers.”
The police investigation into Bobbi Kristina's death is technically still ongoing, but while Gordon was once a person of interest, it now looks as though he will not face criminal charges.
He will, however, soon be forced to give his side of the story in court.
Gordon is being sued for wrongful death by Bobbi's estate.
Lawyers for her family allege that Gordon beat Bobbi Kristina and "injected her with a toxic mixture" moments before she passed out face-down in a bathtub.
No trial date has been set for that civil case.
