Cali Swag District rapper JayAre died on Friday (June 6).

Rising California rapper Cobe Obeah broke the news via Twitter the same day.

According to a source who spoke to MTV News, 25-year-old JayAre (born Cahron Childs) suffered from sickle cell anemia and was admitted to the hospital on Thursday night for unknown reasons. While in the hospital JayAre fell into cardiac arrest and died.

Tragically, JayAre is not the first Cali Swag District member to pass away at an early age. In May of 2011, CSD member M-Bone was murdered in a drive-by shooting.

The group, which started out as a foursome, are best known for their platinum 2010 hit "Teach Me How To Dougie." A year after their breakout smash, the group's dancer M-Bone was murdered, leaving Smoove, Yung and JayAre to carry on and release their debut album, The Kickback.

Earlier this year, CSD dropped a mixtape titled The District, which featured collaborations with Nipsey Hussle, Ty Dolla $ign, Waka Flocka Flame and Skeme.
