'Foul Play' Probed in Bobbi Kristina Case Investigation focuses on boyfriend Nick Gordon, sources say By Neal Colgrass, Newser Staff Posted Feb 6, 2015 7:49 PM CST 19 comments Comments In this Aug. 16, 2012 file photo, Bobbi Kristina Brown, right, and Nick Gordon attend the Los Angeles premiere of "Sparkle" at Grauman's Chinese Theatre in Los Angeles. (Photo by Jordan Strauss/Invision/AP, File) (Newser) – Bobbi Kristina Brown's case is tragic, but accidental—right? Law enforcement officers in Georgia aren't so sure, TMZ reports. Sources say a criminal investigation is focusing on Brown's boyfriend Nick Gordon and the pair's reportedly violent relationship. More specifically, authorities are looking into injuries sustained by Brown and a possible argument between them an hour before Brown was found unresponsive in a bathtub. Sources say Brown's friend Max Lomas hung out with Gordon last Saturday, and thought nothing of it when Gordon wandered off for a while. Soon after, Lomas found Brown in the tub and Gordon "ran in and administered CPR," says TMZ. "We're told Max claims Nick allegedly cleaned up the home and removed blood stains." Police have reportedly interviewed Gordon and Lomas, but Lomas wants immunity before consenting to another interview sought by investigators. And Nick Gordon is said to have "lawyered up." Two days ago, CNN reported that father Bobby Brown's lawyer said, "We are currently investigating the events that led to (her) hospitalization." What's more, police had responded to report of a fight at Brown's residence on Jan. 23, but nobody answered the door and police saw no signs of an altercation. Police told CNN that Brown's case was considered a medical incident, and no evidence of drugs or alcohol were on the scene. At this point, who knows whether this is related to a brawl that broke out between family members.
