It was last January whenshe was was found unconscious in the bath tub at her Atlanta townhouse.

The latest update on  Bobbi Kristina Brown, daughter of late Whitney Houston and Bobby Brown, is that she remains unresponsive in the hospital until now for suffering irreversible brain damage.

No charges have been filed against anyone, even though there are some injury marks that were found in Kristina's body. However, her boyfriend Nick remains the suspect and Kristina's family forbids him of seeing Krissy.

Ian Halperin, author of 'The Deadly Price Of Fame'   the book about the life of Whitney and Bobbi Kristina says he can help Nick, only in one condition, he must pass a polygraph test, Entertainment reports.

Almost all of Kristina's family believe that Nick Gordon has something to do with the incident, the author thinks that if he pass the polygraph test accurately, Gordon will clear his name and prove his innocence.

While Nick Gordon hasn't given any comment yet about the challenge a source told Radar Online that the family are planning to take Kristina home back in Georgia, where she can die peacefully after four months of being unresponsive in the hospital. They want to bring her back to her Mom's home.

According to officials, Bobby Brown is against the family's decision as he does not want to bring home his daughter and take his 22 year old daughter off the life support.
