Law enforcement sources told TMZ that certain injuries sustained by the 21-year-old has led them to investigate if there was any foul play involved in the case - with the focus being on boyfriend Nick Gordon.
Police are reportedly looking into a possible altercation that could have taken place between Bobbi and Nick before she was found submerged in a bathtub last weekend.
After Bobby was discovered unresponsive in a bathtub by Gordon and his friend, Max Lomas, the latter reportedly told police that Gordon cleaned blood from his house before emergency services arrived.
These allegations have not been confirmed and Nick has not made a comment to the press on them.
Bobby, whose mother Whitney Houston was found dead in a bathtub in 2012, remains in a coma following the tragic events last weekend.
Her family have remained tight-lipped about her condition, although cousin Jerod Brown did update fans on social media in a heartfelt post.
‘It seems the odds are against her’ he wrote, also adding: ‘doctors don’t see any hope for change.’
He urged everyone to ‘STILL PRAY FOR BK’ and has even started a hashtag to stay positive in light of the terrible circumstances.
