The California Supreme Court held last month in People v. Prunty, S210234, that when the prosecution seeks to prove the street gang enhancement (Pen. Code, sec. 186.22(b)) by showing a defendant committed a felony to benefit a given gang, but establishes the commission of the required predicate offenses with evidence of crimes committed by members of the gang’s alleged subsets, it must prove a connection between the gang and the subsets. This is a good decision when dealing with gang subsets and the STEP Act and sets forth what the prosecution must show to establish a defendant acted for the benefit of a gang.
