Before little T'Rhigi "Ralo" Diggs was killed in a shooting in DeKalb County, he met 2 Chainz. The Atlanta rapper is now as disgusted as many others who learned of the boy's fate.

“frankly I’m just appalled man,” he wrote in a post on Instagram, with a photo he took with the child, apparently at a public appearance. “this kid is around the same age as my son and my heart goes out to his family.”

The 3-year-old died Sunday night when someone fired a gun into the SUV his mother was driving along Bouldercrest Road near a Texaco station, police said. He had been sleeping in the back seat in his car seat.

Initially, police described the shooting as a drive-by, though they are now also weighing the possibility that the shot came from the gas station parking lot. Detectives hope speaking with possible witnesses at the gas station could add clarity.

So far, police and the mother, Roshonda Craig, have said they felt the shooting could’ve been a hit gone wrong. Detectives don’t believe the child or mother were the targets and that the shooter thought someone else was behind the wheel.

2 Chainz seemed sickened.

“... we have to do better y’all,” he wrote. “how you kill a 3 year old bru ????? How ??? I believe in protecting yourself but I don’t believe in reckless conduct like this I hate it.”
