Foul Play? Police Investigate Bobbi Kristina's Longtime BF Nick Gordon

Nick Gordon is reportedly under investigation, after police found suspicious injuries on Bobbi Kristina Brown's body.

Law enforcement sources told TMZ that police are looking into the possibility of an altercation between Nick and Bobbi Kristina more than an hour before she was found face down and unconscious in a bathtub in her Roswell home.

The couple's friend, Max Lomas, told authorities that he arrived at the home around 9 AM. He hung out with Nick, but was told Krissy was in the bedroom. At some point, Nick left to go to another part of the house. A cable rep knocked on the door and Max let him in.

When the serviceman said he needed access to the bedroom, Lomas showed him the way. That's when he discovered Bobbi Kristina in the bathtub. He pulled her from the tub, called 911, and yelled for Nick, who gave her CPR.

According to TMZ, Max is claiming Nick cleaned up the house at some point, and even removed bloodstains.

Now, Nick is lawyered up and Max, who has a history of arrests, wants immunity before he speaks with the police again.
