A number of media outlets are reporting that Nick Gordon, the boyfriend of the late Bobbi Kristina Brown, faces a possible murder charge in connection with the death of the daughter of Whitney Houston and Bobby Brown.

Bobbi Kristina Brown was found by Gordon and a friend face down in a bathtub in her Georgia home in January, and was later placed in a medically induced coma. She died July 26 at age 22.

Her mother, Whitney Houston, died in a hotel bathtub in 2012.

In the months since Bobbi Kristina Brown’s death, Gordon, 25, has been accused of wrongful death and has been targeted by a civil lawsuit filed by a conservator for Brown.

“In the lawsuit, which seeks at least $10 million in damages, Gordon is accused of giving Brown a ‘toxic cocktail’ the night of Jan. 31, which left her ‘unconscious’ and ultimately led to her … death,” Us magazine reports, noting that the suit also accuses Gordon of beating Brown and withdrawing funds from her accounts.

In the latest development, Us cites an inside source saying the D.A. in Georgia has convened a secret grand jury with the idea of exploring murder charges against Gordon.

“The D.A. does not know what the charges will be yet, but they want to go for murder charges, the source explains to Us, adding that Gordon will be charged with criminal charges ‘very soon.'” the publication reports. “The D.A. is also consulting with legal experts to see if murder charges would stick, the insider continues.”

Gordon’s legal team has vigorously denied the accusations in the lawsuit against him. People magazine reports that his team recently issued a statement in which it said: “The recent lawsuit against Nick is slanderous and meritless. Nick has been heartbroken and destroyed over the loss of his love, and it’s shameful that such baseless allegations have been presented publicly.”

The statement adds: “Nick has engaged civil counsel and intends to defend the lawsuit vigorously and expose it for what it is: a fictitious assault against the person who loved Krissy most.”
