Metro is still using their Open Sky (even though they announced they're going to can it) so no radio traffic.
This occurred at 4:30 AM, the location is in the county so if you were listening you would've heard Clark County Fire. A private ambulance, probably AMR, was also visible at the scene so they cold have been heard as well. LVMPD, probably not.
