“On Thursday, 5 September 2024, the Fulton County Medical Examiner was notified by Grady Memorial Hospital of the death of Dequantes Devontay Lamar,” the statement read.

An autopsy was scheduled for the following day, Friday, September 6.

TMZ was first to break the news of his death.

The rapper’s family confirmed the news of his passing to the outlet, saying they were heartbroken and shattered by his unexpected death.

Quan was at his Atlanta home when his girlfriend found him unresponsive and later foaming from his mouth, according to audio of a 911 call obtained by TMZ.

Quan’s girlfriend told a 911 dispatcher that the rapper fell asleep on the couch on Wednesday night and never came to bed with her. On Thursday morning, she found him still sleeping on the couch.

The musician’s significant other left the house to take her son to school but put a blanket over Quan before she did, presuming he was still asleep. When she returned, she realized he still hadn’t moved. He wasn’t breathing, didn’t have a heartbeat and foamed at the mouth when she turned him over, she told 911.

Shortly after news of his death broke, rumors began to spread on social media that the rapper had passed away following a drug overdose.

Rapper Boosie Badazz was among the first to claim Quan’s death was drug-related.

Rich Homie Quan made a name for himself with his 2013 hit, “Type of Way.” The track landed a spot on the Billboard Hot 100 chart.

He worked with several high-profile Atlanta artists during his career, including 2 Chainz and Jacquees. He was also a part of the Cash Money Records project, “Rich Gang,” along with Young Thug.

Bizarrely, Quan’s name was invoked at Young Thug’s RICO trial just days before his death.
