Busy Day In Henderson For First Responders

It's been a fairly busy day for the normally quiet Henderson, NV.
Early this afternoon, a large house under construction burned down near Mannion Middle School, with the smoke being seen all over the Las Vegas Valley.
Currently, in our neighborhood, Henderson and Las Vegas Metro SWAT are running around in a gated community, near Horizon Ridge and Gibson.  Not sure what is going, other than there was the Sheriff's helicopter flying around, City of Las Vegas Fire heavy rescue truck and cops running around with semi-automatic rifles.
Will find out more, if I can.
Update: Even though there were two SWAT teams, about 30 police vehicles, at least 2 fire department vehicles, cops running around with shot guns and semi automatic rifles across the street from a busy park, there is nothing in the local media about what happened.  Great job media.
It appears the situation ended around 11:30 PM, but there were still police vehicles in front of the house and a park parking lot filled with police vehicles, about 25 or so. 
Hopefully, the morning news will have something.
