Two alleged leaders of a violent Houston street gang have been convicted in federal court for ordering a retaliatory drive-by shooting in the Third Ward that killed an innocent bystander, according to the U.S. Attorney's Office.

A federal jury found Shaquille Richards, 32, and Alexandra Nicks, 32, both of Houston, guilty Monday of using a firearm to kill during a racketeering murder and murder in aid of racketeering.

Prosecutors said Richards and Nicks led the 103 street gang, which had been engaged in a violent feud with the rival Young Scott Block (YSB) gang.
