LOS ANGELES • A lawsuit filed last Friday by the conservator of the late Bobbi Kristina Brown, daughter of singer Whitney Houston, accuses Brown's boyfriend of giving her a "toxic cocktail" and putting her face down in a bathtub before she went into a six-month coma and died.
The 22-year-old, the only child of Houston and singer Bobby Brown, died on July 26 after suffering irreversible brain damage in a still unexplained incident at her Roswell, Georgia, home.
The complaint was originally filed on June 24 in Fulton County Superior Court in Georgia by Bobbi Brown's court-appointed conservator Bedelia C. Hargrove and an amended complaint was submitted last Friday.
It accuses Brown's boyfriend at the time of her death, Nick Gordon, of assault, battery, intentional infliction of emotional distress and stealing more than US$11,000 (S$15,230) from her after she went into a medically induced coma.
The amended complaint also accuses him of wrongful death.
The document describes an argument that allegedly took place between Brown and Gordon after he came home in the early hours of Jan 31, when her body was found in a bathtub.
The lawsuit says Gordon, who had been "out all night on a cocaine and drinking binge", came home and accused Brown of cheating on him during a "loud argument" that lasted about 30 minutes.
According to the complaint, Gordon then "gave Bobbi Kristina a toxic cocktail rendering her unconscious and then put her face down in a tub of cold water causing her to suffer brain damage".
He allegedly came out of the bedroom wearing different clothes, laid his head on a female guest's ankle and said: "Now I want a pretty little white girl like you."
A guest in the house allegedly found Brown in the bathtub and, according to the lawsuit, she was "unresponsive, unconscious with a swollen mouth and a tooth hanging loosely from her mouth".
Gordon then allegedly came in, let the water out of the tub and said "clean up, clean up", as guests attempted to give Brown mouth- to-mouth resuscitation.
"After almost six months of suffering, Bobbi Kristina died from" Gordon's actions, the lawsuit says.
A spokesman for Gordon's defence lawyer Jose Baez said the lawsuit was "slanderous and meritless", reported USA Today.
"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 spokesman said.
Brown's death was an eerie echo of that of her mother, who drowned in a bathtub at a Beverly Hills hotel in 2012 at age 48.
She was buried last Monday alongside her mother.
