Lawrence “Big Law” Loggins has been the head of Chicago's notorious gang the Black Disciples since he was released from prison in 2009. Now he's dead. Big Law, who was 46 and considered an 'OG', was reportedly murdered by young members of his gang.

Police say that Big Law was trying to consolidate power before he was assassinated Wednesday night - by some teenage members in his gang.

Now the Chicago Police Department is bracing for a potential bloodbath on the South Side in retaliation for Loggins’ murder. Police are doing everything possibly, including investigating Big Law's murder, to try to prevent revenge killings.

Social media was buzzing on Friday about the possible motive for Bug Law's murder. Rapper Lil Durk, a popular Chi-town rapper, tweeted out “RIP Big Law.”

Big Law was shot in the head at 9:08 p.m. Wednesday on the South Side of Chicago. He was found face-down on the driver’s seat of the SUV.

A man wounded in the shooting told police the assailants ran through an empty lot and fled in a gray Infiniti sedan.

Here's why the Chicago Sun. Times claims he was killed:

From the 1970s through the mid-2000s, the gang’s leaders had issued orders to lower-level members through a rigid hierarchy.

Gang experts have estimated that 15,000 people were members of the Black Disciples during that period. Low-level members who ignored orders were beaten or k*lled and were required to pay a “street tax” from the proceeds of their drug deals and other crimes.

Today, independent factions of the Black Disciples operate on the South Side and the younger generation of members has bristled at the idea of losing their autonomy, sources said.
