If Bobbi Kristina Brown dies, her boyfriend Nick Gordon could be investigated for murder, TMZ reports.

The Fulton County District Attorney told the gossip site: "In view of the new circumstances regarding the health status of Bobbi Kristina Brown, we will be reviewing the case with greater interest."

A source told FOX411 "The DA had assured [the family] that they have been investigating and will certainly step up efforts to present case to grand jury now that [Bobbi] is expected to pass anytime now. Nick Gordon is their primary -- if not only-- target." 

TMZ reported that shortly after Brown was found unconscious in a bathtub on Jan 31, prosecutors began investigating Gordon because bruising was found on the 22-year-old’s body.

Brown’s aunt Pat Houston told the press on Wednesday that her niece was in hospice care. A source told FOX411 that the family had made the decision to "unhook everything, no medication, anything."

The source continued, "It is literally anytime now before she's pronounced dead, unfortunately."

Pat Houston’s solemn statement added, “She is in God's hands now."

On Wednesday a court-appointed representative for Brown filed a lawsuit against Gordon, claiming he took money from her and abused her physically and emotionally.

Gordon is accused of assault, battery, intentional infliction of emotional distress, unjust enrichment and conversion in the suit, which seeks $10 million in damages.

The Fulton County DA did not immediately return FOX411’s request for comment.

Brown has been in various hospitals since she was discovered in her home unconscious on Jan. 31 by Gordon and a friend. She is the daughter of singer Bobby Brown and the late Whitney Houston, who died after drowning in a bathtub.
