Bobbi Kristina’s Boyfriend, Nick Gordon, To Be Charged With Manslaughter

Nick Gordon, who was the boyfriend of the late Bobbi Kristina, is now in serious trouble as prosecutors want to charge him with involuntary manslaughter, and are trying to use one of Nick's friends to turn him in law enforcement sources told TMZ.

TMZ's sources say authorities believe Nick's alleged crime is arranging to get drugs for Bobbi Kristina the day she almost drowned in her bathtub. Nick already confessed to the fact that both he and Bobbi did drugs that morning, but now sources tell us there was nothing intravenously injected.

The autopsy is not helping authorities make their case because it showed no obvious signs of foul play and the toxicology reports will only determine if she was under the influence and not who supplied the drugs.

The key for prosecutors is the third person in Bobbi Kristina's home that day, Max Lomas, who's currently being prosecuted in Georgia for 2 drug-related felonies, not connected to Bobbi Kristina.

Lomas' case has lingered for nearly 6 months, and one source familiar with the case tells us, authorities are interested in offering Lomas a deal, probation on the drug charges and immunity in the Bobbi Kristina case in return for spilling all the details of what happened in her house.

We're told prosecutors believe Nick had reason to know Bobbi Kristina had a drug problem and also knew she would indulge to the point of losing consciousness, yet he helped her get and use drugs and then left her in harm's way.

The boy has found himself in serious gbese!
