Young Thug's nephew is in police custody, accused of killing his girlfriend. The hip hop website has learned something. Police were called to a residence outside Atlanta. When East Point police arrived, they found a dead woman by the front door and a crying Grier by the side of the road. It's not clear why he chose to give the information to the police. The relation is confirmed by a source. We're told Grier first told responding officers he was fending off 2 armed, masked invaders, but later admitted to shooting the girl in the face. There was an argument in the residence before the shooting. The man was arrested and charged with a crime. Young Thug is being held on a wide range of RICO charges after being denied bond many times. The YSL artist, who is also charged in the RICO case, was in court trying to get out of jail, but a judge shot it down. We reached out to Young Thug's legal team for comment, but so far they have not responded.
