The administrator of Bobbi Kristina Brown’s estate added a wrongful death count to the lawsuit against Nick Gordon. It accuses Gordon of giving Brown a “toxic cocktail” and putting her face-down in water.

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

Gordon hasn’t been criminally charged. The Fulton County Medical Examiner’s office has said an initial autopsy revealed “no significant injuries.”
