Bobbi Kristina Brown's boyfriend Nick Gordon may well face criminal charges related to her untimely death, and Max Lomas may play a key role.
Bobbi Kristina almost drowned in her bathtub at home January 31, when she was found by Gordon and Lomas. She never regained consciousness.
Gordon is in the crosshairs of prosecutors, and has been since day one, but it's looking like he may escape without being charged with murder.
Being charged with involuntary manslaughter is likely, however.
Law enforcement sources say Nick's alleged crime is not throwing Bobbi around and causing the facial injuries she was reportedly found with.
Rather, it's arranging to get drugs for Bobbi Kristina that day.
We know Bobbi Kristina had a history of falling asleep in the tub, and that Nick has told relatives that he and Bobbi both did drugs that morning.
There were no substances intravenously injected and no obvious signs of foul play, likely ruling out any proof that Nick wanted Krissie dead.
But those facts won't get him off the hook entirely.
The key to the case, TMZ reports, is Max Lomas.
The third person in her home that day, he's currently being prosecuted in Georgia for two drug-related felonies not connected to Bobbi Kristina.
Lomas' case has lingered for six months. Possibly by design, as authorities are considering letting him cop a plea for probation and that's it.
In exchange? He testifies against Gordon.
For a wrist slap in the drug cases and immunity in the Bobbi Kristina case, he would be their star witness in revealing what happened to her.
Prosecutors believe Nick had reason to know Bobbi Kristina had a drug problem and knew she would indulge to the point of losing consciousness.
Despite that, he enabled her on that day. Doesn't sound like the strongest case, but remember, we haven't heard from Max - or Nick - directly.
