From the article timeline, it took 39 minutes to locate and arrive on scene of the crash (7:29p to 8:08p), so that was, for that area, a good response time.
It will take time for the NTSB (National Transportation Safety Board) to investigate and attempt to determine cause(s) and solutions. It is very probable that this helicopter had the post-mortem orange boxes for the inquest.
Helicopters are marvelous machines, so capable of wondrous feats of flying! But everyone involved in their operation knows that maxim that the machine is basically a collection of unwilling parts flying in close formation until they don’t!
RIP for these professionals and especially for their families and friends!
The helicopter was a rebuilt Vietnam era chopper. One report is that it was not so equipped.
This chopper was the one that assisted in the rescue of 21 people from two stuck Sandia Peak tram cars on this past New Year's day.
Three scenarios come immediately to mind: There were thunderstorms reported in the area, a possible microburst; the chopper had just refueled at the Las Vegas airport (but had also done so earlier too); or shot down by local redneck idiot (another was shot at in ABQ a couple of years ago).
