On January 31, 2015, Gordon and a friend found Brown face down in a bathtub in her home in Alpharetta, Georgia. They began CPR until emergency medical services personnel arrived. According to a police spokesperson, Brown was alive and breathing after being transported to North Fulton Hospital in Roswell, Georgia. At first, they found no evidence to indicate the incident was caused by drugs or alcohol, but this later was disputed. Doctors placed Brown in an induced coma after determining her brain function was "significantly diminished", and her family was told meaningful recovery would be "a miracle".
During a radio interview on March 25, 2015, Brown's grandmother, Cissy Houston said Brown's condition remained the same and that there was "still not a great deal of hope. We're praying." Brown was moved to an Atlanta rehabilitation facility in March 2015. After Bobby Brown told concertgoers in April that his daughter was "awake", Cissy released a statement saying her granddaughter was no longer in a coma, but remained unresponsive. Doctors said Brown had "global and irreversible brain damage".
In June 2015, Bobby Brown arranged to have his daughter flown to Chicago to be seen by specialists, only to be told that nothing could be done. She was flown back to Atlanta, and moved to Peachtree Christian Hospice in Duluth, Georgia on June 24. Her aunt, Marion Garland (Houston), stated that Bobbi Kristina's condition had continued to deteriorate.
Brown died in hospice care on July 26, 2015, at the age of 22. The initial autopsy found no "obvious underlying cause of death and no significant injuries", and the Fulton County Medical Examiner's office said more tests were forthcoming. A statement released by the family thanked "everyone for their tremendous amount of love and support during these last few months". Several prominent celebrities offered their condolences, including Chris Brown, Oprah Winfrey, and Whitney Houston protegées Brandy and Monica. Funeral services were held August 1, 2015, at St. James United Methodist Church in Alpharetta, Georgia. Brown was buried two days later between her mother and maternal grandfather at Fairview Cemetery in Westfield, New Jersey.
The Fulton County Medical Examiner's office announced on September 25, 2015, that it had "classified the cause and manner of Bobbi Kristina Brown's death", while citing a Superior Court order that prevented the office from releasing any details to the public. The findings were provided to the Fulton County District Attorney and to Roswell Police.
