With Bobbi Kristina Brown’s health reportedly deteriorating in recent days, all eyes are on her former boyfriend Nick Gordon, who, in a worst-case scenario, could become a person of interest in a murder investigation associated with the January incident that led to her current condition, according to TMZ. Now, the family’s unofficial biographer is claiming that people don’t know how bad the Gordon case is actually getting.

It was previously reported that police were taking a close look at the circumstances surrounding the incident that put the daughter of music icon Whitney Houston into a medically induced coma for several months. Rumored to be part of this probe is Bobbi Kristina’s former boyfriend, Gordon. Although police have not officially labeled him a person of interest in the potential murder of the 22-year-old, a lawsuit filed by her conservator, Bedelia C. Hargrove, alleged Gordon physically abused Bobbi Kristina, manipulated her bank accounts so he could have control over her money and began to exercise his authority when it became clear she was about to leave him.

The author of the unauthorized biography “Whitney & Bobbi Kristina: The Deadly Price of Fame,” Ian Halperin, is now claiming there’s a lot more to the story than physical abuse and the alleged theft of $11,000 while Bobbi Kristina was in a coma.

“This is a clear-cut case of negligence, of abuse, of foul play,” Halperin told Entertainment Tonight. “And, right now, Nick Gordon is shaking in his boots. I have spoken today to members of Bobby Brown’s family, and they want justice immediately.”

Halperin is claiming not only that the duo were hooked on drugs during the final days of their relationship but also that the amount allegedly stolen by Gordon came to way more than the $11,000 the lawsuit is seeking to recover.

“They had joint accounts. Nick insisted on it,” Halperin told Entertainment Tonight. “There were fancy cars. There was fancy jewelry. There were trips. We won’t know until a proper investigation is done. But I’ll tell you right now it’s much more than $11,000.”

It’s worth mentioning that the family’s unofficial biographer is hardly a reliable source for such information and that nothing will be known for certain until the investigation is complete.
