ATLANTA (AP) - The ex-partner of the late Bobbi Kristina Brown, has died. Nick Gordon was 30 years old.

Gordon's attorney confirmed his client's death in a statement to The Associated Press. He did not give a cause of death.

Brown was the daughter of singers Whitney Houston and Bobby Brown. She was found unresponsive in a bathtub in 2015 and died after months in a coma.

Investigators were not able to determine exactly how Brown died. Her family blamed Gordon, accusing him in the lawsuit of giving her a “toxic cocktail.” Gordon was never charged in the case, but he was found responsible in a wrongful death lawsuit.
