Michael Brown was shot and killed in Ferguson, Missouri a year ago (09Aug14) after he was caught up in a store robbery investigation.

Violence erupted on the streets of the town and across America shortly after the incident hit the headlines, and many celebrities from the hip-hop world reacted to Brown's death.

Now, a year after the shooting, some stars still have the slain youngster in their thoughts.

Common took to Twitter on Sunday and wrote, "A year ago #MikeBrown's life was taken for no reason good enough. Now we fight to change America in his honor."

The Roots star Questlove added, "#FergusonTaughtMe everything is just fine... right?"

Talib Kweli, Chance The Rapper and Outkast's Big Boi also posted tributes linked to Brown, while Def Jam co-founder Russell Simmons tweeted, "Let's show the #Ferguson community that we stand with them! Send your message of solidarity + love using #DearFerguson!".
