The lawsuit also accuses Gordon of battery, assault, infliction of emotional distress and embezzlement.
Newly released documents in the Brown family lawsuit accuse Nick Gordon of injecting Bobbi Kristina Brown with a "toxic mixture" shortly before she was found facedown in a bathtub last January.
According to USA TODAY, the new accusation comes on top of the mounting claims against the 22-year-old's boyfriend. Bobbi Kristina's estate has accused Gordon of battery, assault, intentional infliction of emotional distress and embezzlement.
"Ms. Brown died due to a violent altercation with Defendant (Gordon) after which he placed her in a bathtub, unconscious, after he injected her with a toxic mixture," reads the filing.
This comes just days after Gordon filed a motion requisition that a judge halt the civil lawsuit. Gordon's attorneys are denying all the claims.
