Panther's murderer

A continuation of the mission to hunt down the Last Day troublemakers in Cordon.
==Walkthrough==
Marked One will contact Klyonov and ask him if he still has the Photo-Gun. Klyonov will readily teleport it to the staircase leading to Sidorovich bunker.
Ghost will also message and tell you that he had a fight at Generators with several invisible men from the Last Day Hog told you about, and that Maximilian escaped his watch and ran away somehow.
Marked One will send a message to Chernomor, asking him about the properties of the Photo-Gun. Chernomor calls him for a talk.
Head to Yantar and speak with Chernomor. He says that the Photo-Gun was created by the blind weaponsmith from Last Day, and that every Last Day member has a mark which is visible in the Photo-Gun viewfinder. He'll give you a photograph of the loner village in Cordon that shows where the user of the Photo-Gun is to stand.
Go back to Cordon and stand on the corner of the building circled in the photograph. BUG WARNING: Unequip your primary gun!. Focus the Photo-Gun on the target in red, and shoot. The resulting photograph will have a stalker highlighted in red with the word "Scram" printed underneath.
Find the stalker named Scram by the campfire, wearing a brown leather jacket and balaclava. Exhaust his dialogue where he gives himself up but still feigns ignorance of the greater picture.
Talk to Panther's father, give him the photo, and the Intruder task starts.
==Notes==
* Scram carries an IMI UZI, an unusual weapon even if he is undercover.
* It's unclear how Marked One figured out to use Photo-Gun to find the infiltrator, in the first place. It looks like an oversight.
