I live in the area. Crazy how many helicopters and drones showed up so quick and how many police there were. For several hours more and more police and FBI vehicles kept arriving. Probably ended up with close to 100 officers on scene. Salem NH PD, Methuen MA PD, Providence RI PD, NH state police, MA state police, FBI, and US Marshal service were the ones I saw.
I think it's the biggest response I've personally seen since the Boston Marathon Bombing.
Same perspective here just 15 miles northwest of scene. Pretty sure they confirmed officially presence of MA NH LEO, NHSP, MASP, FBI, CIA, ATF, and Secret Service.
all of that and they basically just got lucky. the guy walked to brown from his car parked nearby and shot up some kids, waited days, went to a guy's house in Massachusetts, killed him and never even got caught - he committed suicide and was only found days after his second killing
if anything this whole saga makes me happy smart people aren't killers more often because this guy basically got away...
