Whitney Houston and Bobbi Brown's only daughter, Bobbi Kristina Brown, is still on life support after being rushed to the hospital last Saturday (Jan. 31). The 21-year-old was found face down in a filled bathtub by her partner, Nick Gordon, and a friend.

Police have launched an investigation into Brown's hospitalization and are reportedly shifting their focus to Gordon. According to CNN, family sources said Brown has injuries that need an explanation. The source would not say what type of injuries or where they were found.

Shortly after Brown arrived at North Fulton Hospital, she was placed in a medically induced coma to help with swelling on her brain. She was later transferred to Emory Hospital in Atlanta to receive further treatment. Doctors don't know the status of Brown's brain function and can't determine the severity of her condition until she is taken out of the coma.

It was reported that doctors wanted to reduce Brown's sedatives last week but decided against it. A source told CNN that Brown briefly opened her eyes on Monday but she also suffered seizures that same day.

On Friday, her grandmother Cissy Houston arrived in Atlanta and was seen heading into Emory Hospital with other family members. Brown's father, Bobby Brown, has been in Atlanta with his pregnant wife for the past week.

Gordon was also spotted standing outside the hospital but sources said that he has since been banned and is not allowed to see Brown. Her almost-drowning is eerily similar to the way her mother, Whitney Houston, died. The 48-year-old was found in a bathtub at the Beverly Hilton hotel on Feb. 11, 2012.

A coroner listed accidental drowning as the cause of death for Whitney and said cocaine use and heart disease were also contributing factors.
