ATLANTA (AP) -- The administrator of Bobbi Kristina Brown's estate has added a wrongful death count to the lawsuit against her partner.

The amended lawsuit filed Friday also accuses Nick Gordon of giving her a "toxic cocktail" and putting her face-down in water.

The 22-year-old daughter of Whitney Houston died in hospice care July 26, about six months after she was found face-down and unresponsive in a bathtub in her suburban Atlanta townhome Jan. 31.

Gordon hasn't been charged criminally. It was not immediately clear Friday who his lawyer is.

An initial autopsy found no obvious cause of death and the medical examiner's office said it would likely take several weeks to rule on a manner and cause of death.

The district attorney has said they will review the investigative file.
