Nick Gordon is reportedly a person of interest in what now is considered a homicide investigation in the wake of Bobbi Kristina Brown’s passing on Sunday. Gordon has been the subject on an investigation ever since Bobbi Kristina was found unconscious in a bathtub in her Roswell, Georgia home back on January 31.

A $10 million civil lawsuit was filed against Nick Gordon recently. It alleges he physically and mentally abused Bobbi Kristina Brown, and withdrew money from one of her bank accounts as she lay in an Atlanta hospital in an induced coma.

Nick Gordon often claimed that he and Bobbi Kristina were married. Bobby Brown denied his claims after his daughter was hospitalized. No one has ever found proof that the two legally wed.

Now both the Roswell, Georgia D.A. and the police department there are treating the Bobbi Kristina Brown case as a homicide.

Earlier in July, a close friend of Bobbi Kristina–Alex Reid–said Nick Gordon had, in fact, abused Bobbi Kristina Brown on more than one occasion.

“I don’t know when he started hitting her,” Alex said. “But I know of at least four occasions when he struck her. She also told me about he had tried to choke her once. She was definitely scared. She had some friends, but not many. One time, I remember she called me for three hours. She was hyperventilating. I could barely understand what she was saying because she was so distraught. When she could finally get the words out, she told me he had been physically abusive. He had hit her in the face and thrown her against a wall.”

After learning about Nick Gordon’s abusive history with Bobbi Kristina, he was prevented from visiting her in the hospital by her dad, Bobby Brown.

Nick Gordon was said to be on a suicide watch in the wake of Bobbi Kristina’s passing Sunday. His father has since denied the claims. He says that while his son is distraught, he isn’t suicidal.
