An initial autopsy on Bobbi Kristina Brown on Monday found no significant injuries and no obvious underlying cause of death for the daughter of the late singer Whitney Houston, who died on Sunday after sustaining irreversible brain damage in January.
The Fulton County medical examiner's office in Georgia said Brown (22) had no previously unknown medical conditions . It also said it has issued subpoenas to help gather documentary information on her death.
Brown, the only child of Houston and R'n'B singer Bobby Brown, died at a hospice where her family had placed her a month ago after giving up hope she would recover. She died six months after an unexplained incident that left her unresponsive in a bathtub in her Atlanta home.
The medical examiner said officials would conduct additional tests that are expected to take several weeks. Officials had said earlier their efforts to determine what happened to Brown in January would be "challenging" given the time gap between the bathtub incident and her death. She was found face down in the bathtub by her boyfriend, Nick Gordon, and a friend on January 31st.
