Rich Homie Quan was born and raised in Atlanta, and attended college on a baseball scholarship before the costs of school became unsustainable. In his early 20s, he was sentenced to 15 months in jail in connection with a burglary, and after his release he began to pursue music as a career. His 2013 breakout hit "Type of Way" catapulted him to fame, while collaborations with both his peers and his idols helped keep him on the charts in the following years. Some of his other hits include "Flex (Ooh, Ooh, Ooh)," "Lifestyle" and "Ride Out."

According to local Atlanta outlet 11 Alive, Quan was discovered unresponsive at his home by his girlfriend, Amber Williams. The outlet obtained a recording of Williams' call to 9-1-1, requesting an ambulance. She said: "He never got up. I don't feel a heartbeat, I don't see him breathing. He kind of foamed at the mouth." The medical examiner has conducted an autopsy, and will pronounced a cause of death once lab results come back.

In the meantime, other rappers and colleagues are sharing their tributes to Quan and offering comfort to his friends and family on social media - including Williams and Lamar. The rapper's legacy and his reputation for straightforward friendliness are both evident in the stories and throwbacks circulating online, and Lamar has re-posted many of them.
