Yes, I think that print article tells it all.
Quoting it:
Sources said the modus operandi appears to be such that they come over for a few days and have a strong local network to help with logistics and stay. The group does not remain in the Poonch-Rajouri area long enough for the agencies to track them down. It is believed the same group was behind the terror strike in Dangri in January, they said.
“This group has been operating in this region and is believed to have been behind other incidents too but none have been solved yet,” a second source said.
There have been 13 incidents involving terror groups in this region over the last year and a half and none of them have been solved yet.
Identity of perpetrators not clear yet. Army has launched multiple teams to scan adjoining forest areas close to LoC and about a dozen people have been picked up as part of questioning.

So many questions:
If this was known why did the intelligence not track them down?
Who is the local base providing them support,stay and logistics?
Who are their handlers?
Which routes are they coming from Pak and why are these not plugged?
Where are they getting their arms, weapons from if our security claims to have identified foreign weapons?
Why is the same story of terrorist comes, gets local support and goes away getting repeated?
I am sure NSA and team are tracking them down but question is at what level of sophistication and urgency?
