Atlanta ( CNN ) The daughter of the late singer Whitney Houston , in a medically induced coma after being found unresponsive in January , has been moved to a rehabilitation facility , a source close to the family said Friday . Bobbi Kristina Brown , 22 , had been treated at Emory University Hospital . No details about the transfer to a rehab facility were given . Brown , Houston 's daughter with singer Bobby Brown , was found unresponsive January 31 in a bathtub at her home in the Atlanta suburb of Roswell . The extent of her injuries is n't known . Last month , doctors at Emory removed her breathing tube , allowing Brown to be ventilated through a hole in her throat . At the time , CNN Chief Medical Correspondent Sanjay Gupta said the procedure suggested she would need to be on such support for `` weeks and months to come . '' Police have said they are treating Brown 's case as a criminal investigation . When Houston died in 2012 , she was also found in a bathtub . A coroner ruled her death an accidental drowning , with heart disease and cocaine use listed as contributing factors . Brown is Houston 's only child . Brown 's boyfriend , Nick Gordon , says he performed CPR after finding Brown in the tub . Gordon has complained that Brown 's family has not allowed him to see her , but Bobby Brown said last month that Gordon simply refused to abide by the family 's terms for a visit . CNN 's Sunny Hostin contributed to this report .
