Whitney Houston’s Daughter, Kristina Brown in Medically Induced Coma

The daughter of Whitney Houston, Bobbi Kristina Brown, is on a ventilator and in intensive care, after she was found
facedown and unresponsive in a bathtub full of water, a source close to the family said.

Brown, 21, was placed in a medically induced coma and the status of her brain function won't be known until the sedatives are reduced, the source told CNN.

"It is going to be a waiting game.” Brown
"was not breathing" when a man identified as her husband found her Saturday morning inside her townhouse in the Atlanta suburb of Roswell, Georgia.

He called 911 and performed CPR until public safety officers arrived and took over, said police spokeswoman Lisa Holland. The spokeswoman said when Brown was found, she was "unresponsive, meaning not breathing, no heartbeat."

Nobody knows what caused Brown's
unresponsiveness, Holland said, but police
consider it a medical incident at this time.
She said investigators had found nothing to
indicate it was drug- or alcohol-related. Police had been to the residence recently. Somebody reported a fight there January 23, but nobody answered the door and officers found no
evidence of an altercation, Holland said.

The police spokeswoman noted one oddity in the case: "Her mother died in the very same manner."

Three years ago, Houston was found dead in a bathtub at the Beverly Hilton on February 11, hours before she was to attend a pre-Grammys bash.

An autopsy later revealed that she'd drowned facedown in "extremely hot water" about 12 inches deep. The Los Angeles County coroner ruled it an accidental drowning with the "effects of atherosclerotic heart disease and cocaine use" as contributing factors.
