Bobbi Kristina Brown's condition has not worsened this week

ATLANTA, Feb. 15 (UPI) -- Media reports claiming comatose Bobbi Kristina Brown's condition has worsened this week, with her organs shutting down, are inaccurate, a family member insists.

"There hasn't been a change in the past week," People magazine quoted an unnamed relative as saying Sunday. "Nothing at all. It's not like her kidneys are shutting down or anything. There hasn't been any change."

Bobbi Kristina Brown is Bobby Brown's 21-year-old daughter with his late ex-wife Whitney Houston. She has been on life support for two weeks after she was found facedown and unresponsive in her bathtub at home. The circumstances of her medical emergency remain under investigation.

Police reportedly are looking into whether Bobbi Kristina Brown and her longtime boyfriend Nick Gordon had an altercation shortly before she was discovered in distress. Also being considered is whether a recent car crash in which Brown was involved might have played some factor.

The Houston-Brown family marked the third anniversary of Whitney Houston's death last week. She accidentally drowned in a hotel bathtub while intoxicated Feb. 11, 2012. She was 48.
