Stop Stick Malfunction During Vehicular Pursuit of Shooting Suspect

At 0100 HRS, dispatch aired a vehicular pursuit following a shooting that had just occurred in the area. The pursuit was heading onto a nearby highway at approximately 100 plus mph. I was able to get into the area of [the interstate] and drove southbound down the northbound off-ramp to get into position. I grabbed the Stop Sticks from the trunk of my patrol car as the pursuit was quickly approaching.
