Bobbi Kristina Brown died from a combination of drowning and drug intoxication, the Fulton County Medical Examiner's office revealed in a statement on Friday.
Released on what would have been Brown's 23rd birthday, the statement sheds light on her condition when she was found unresponsive in her bathtub on Jan. 21, 2015.
In a statement released in July, the medical examiner's office indicated the months between the January incident and Brown's death would "complicate reconstruction of the events surrounding her initial unresponsiveness.
Meanwhile, her boyfriend Nick Gordon, 20 - who was raised as Houston's son, but never officially adopted - is in the midst of a legal battle with Brown's family.
Brown's best friend and former roommate Mason Whitaker reflected on the loss of the late Whitney Houston and Bobby Brown 's only child in an interview with PEOPLE in February.
