Mike Beck was a member of the rap collective K.A.R. Kill All Rats, which also featured group members Rob Kash, Onez and Leader.

Sources say that Beck was shot and killed on Logan and Bellmar Street in Brooklyn, and that a botched robbery attempt could have been the motive.

Beck and K.A.R. were featured on Fat Joe’s “300 Brolic” remix. In May, the group released a self-titled mixtape executive produced by Fat Joe and Pistol Pete.

In addition to Fat Joe and Pistol Pete, K.A.R.’s mixtape features guest appearances from Ace Hood, Sheek Louch, Hell Rell, DJ Khaled, Jadakiss and others.

Beck was born and raised in East New York. At the age of 17, he was sent to prison for five years, for his role in a murder.

A number of artists expressed their condolences via Twitter.

“R.I.P. Mike Beck!!!!!” Fat Joe Tweeted, as did Cool & Dre, DJ Khaled, Noreaga, Raekwon and others.
