ATLANTA - An autopsy will be needed to evaluate what led to the death of Bobbi Kristina Brown, daughter of singer Whitney Houston, authorities said Monday, the day after her death.

In a statement Monday morning, the Fulton County Medical Examiner's Office says the time that elapsed from when she was found unresponsive in January until her death Sunday will "complicate" its effort to reconstruct events.

"Interpretation of autopsy findings and other information will also be challenging," the medical examiner's office said in the statement. "However, an autopsy could be helpful to address questions which may arise about the cause of her unresponsiveness and eventual death."

Bobbi Kristina died Sunday at Peachtree Christian Hospice in Duluth, Georgia, about six months after she was found Jan. 31, face-down and unresponsive in a bathtub in her suburban Atlanta townhome. She was 22.

A police report described it as a drowning.

Bobbi Kristina was the only child of Houston and R&B singer Bobby Brown.

"Bobbi Kristina Brown passed away July, 26 2015, surrounded by her family. She is finally at peace in the arms of God. We want to again thank everyone for their tremendous amount of love and support during these last few months," Kristen Foster, a representative for the Houston family said Sunday.

She had been hospitalized for months in Atlanta -- eventually being placed in hospice care -- after being found in a manner grimly similar to the way her megastar mother died three years earlier.

Nick Gordon, who shared her townhome with her, said at the time it seemed Bobbi Kristina wasn't breathing and lacked a pulse before help arrived.

"The Roswell Police Department continues its investigation into the circumstances preceding and surrounding the time of the original incident leading to her death," the medical examiner said in Monday morning's statement.

The medical examiner did not release a time frame for the autopsy, but said additional lab testing might take several weeks.
Born and raised in the shadow of fame and litigation, shattered by the loss of her mother, Bobbi Kristina was overwhelmed by the achievements and demons of others before she could begin to figure out who she was.

Bobbi Kristina -- the sole heir of her mother's estate -- did have dreams.

She identified herself on Twitter as "Daughter of Queen WH," ''Entertainer/Actress" with William Morris & Co., and "LAST of a dying breed." She told Oprah Winfrey shortly after her mother's death in 2012 that she wanted to carry on her mother's legacy by singing, acting and dancing. But her career never took off.

She became a social media sensation, sending more than 11,000 tweets and attracting 164,000 followers.

As the news of her death spread across social media, several celebrities tweeted their condolences.
