As fans know, Houston was found dead at the age of 48 in February 2012 after she accidentally drowned in the bathtub of her hotel room at the Beverly Hilton. The coroner later declared that heart disease and cocaine use also contributed to the seven-time Grammy winner's death.
Nearly three years later, Brown was found unresponsive in a bathtub inside her Georgia home. She was in a medically induced coma for six months before she died in hospice care at age 22 in July 2015. Gordon, who Brown considered her "big brother" before they started dating in 2012, was present when Brown was discovered in the bathtub.
A month after Brown's death, her conservator, Bedelia Hargrove, filed a $10 million wrongful-death civil lawsuit against Gordon, claiming in court documents obtained by Radar Online that the R&B scion died "due to a violent altercation with [Gordon] after which he placed her in a bathtub, unconscious, after he injected her with a toxic mixture." Gordon repeatedly denied the allegations, and has yet to be charged criminally.
Houston's ex-husband and Brown's father, R&B singer Bobby Brown, later responded to the news in a statement to Us Weekly, saying, "I am pleased with the outcome of today's court proceedings. All I ever wanted was answers relating to who and what caused my daughter's death. Today's judgment tells me it was Nick Gordon. Now I need to process all the emotions I have and lean on God to get me and my family through this."
