There was an execution-style shooting in the Taco Bell in Grand Junction last summer which may have been gang related.
Moved away from there 11 years ago.
Back then, there wasn't any notable Mexican gang activity.
I-70 serves as a major drug corridor, and there was certainly a meth problem.
A caucasian biker gang known as the "High Plains Drifters" supposedly controlled much of the trafficking.
All the other "gangstas" appeared just to be wannabes, but they still caused some problems.
Had one such group come in during an "underage night" at the club where I worked.
They behaved while inside, but subsequently shot a kid I bounced earlier in the night when words were exchanged across the street.
The kid hopped in his car and his girlfriend drove him to the hospital a few blocks away, but he bled out from a neck wound on the way.
The shooter and his crew gave chase and shot at them while pursuing.
The driver beat a charge of accessory to murder.
Plenty of other drug-related violence was commonplace in the area, but it never appeared to be gang-related.
Haven't heard of any gang issues from friends and family who still live there.
