Bobbi Kristina -- Life Support Withdrawn Wednesday ... Anniversary of Whitney's Death

10:25 AM PT -- A lawyer for Bobby Brown just issued a statement, saying there is no truth to the story that Bobbi Kristina will be taken off life support Wednesday. As we reported, members of the Brown family informed us that was indeed the case. But the lawyer, Christopher Brown, says it's not so.

Bobbi Kristina will be taken off life support Wednesday ... on the 3rd anniversary of Whitney Houston's death ... TMZ has learned.

Brown family sources tell us Bobby has finally made the decision, realizing there is no hope for his 21-year-old daughter to recover.

A source connected with Houston's family told TMZ on Sunday ... Cissy Houston, Whitney's mom, also wanted life support pulled on the anniversary to "bond mother and daughter for eternity." We have not confirmed this, but the NY Post ran the story Tuesday morning.

Members of the Brown family are extremely emotional, sobbing over the decision but realizing it's the right thing to do.

TMZ broke the story ... police have launched a criminal investigation because Bobbi Kristina had injuries on her body when she was rushed to the hospital and we're told the target of the investigation is her boyfriend, Nick Gordon.
