Bobbi Kristina Brown’s boyfriend Nick Gordon is reportedly the focus of an investigation underway in in Georgia in Whitney Houston‘s daughter’s case.

TMZ has reported the criminal investigation launched this week centers on possible foul play.

Authorities reportedly told CNN that certain injuries sustained by Bobby Kristina Brown “piqued their interest.”

“We do not know the nature of the injuries,” claimed TMZ, but they say multiple sources have said there is a history of violence between the couple.

On Tuesday, an attorney for Bobby Brown issued a statement denying the couple were married and confirming that the family also was investigating the incident.

“We are currently investigating the events that led to the hospitalization of Bobbi Kristina,” Christopher Brown of Brown & Rosen LLC said in the statement. “To correct earlier reports, Bobbi Kristina is not and has never been married to Nick Gordon.”

Police are said to be looking into a possible altercation that may have occurred more than an hour before Bobbi Kristina was found submerged facedown in a bathtub.

Max Lomas, the friend who discovered Bobbi Kristina in the tub, reportedly arrived at her home around 9 a.m. on Jan. 31.

TMZ reports that Lomas said he hung out with Nick, but Bobbi Kristina was nowhere to be found. When he asked where she was, he was told she was in the bedroom. Nick apparently then wandered away, but Lomas told the website he didn’t pay attention to his whereabouts.

The website further claims a cable technician arrived shortly after 10 a.m. and Lomas said he let him in. When the technician said he needed access to the bedroom, that is the moment when Gordon discovered Bobbi Kristina facedown in the tub. Lomas said he screamed for Gordon, who ran in and administered CPR before first responders arrived and continued attempts to resuscitate Bobbi Kristina.

TMZ further reports that Lomas claims Nick Gordon allegedly cleaned up the home and removed blood stains.

Roswell Police Chief Rusty Grant told People magazine that the police are “going to follow the evidence and see where it leads us.”
