Help With AI Blueprint

Hey there, im fresh to unreal engine 4. I want to set up an itneraction where when the player runs in to a trigger, it spawns the AI demon, makes it walk across the path the player is on, and than despwan once the demon has walked behind some trees and is out of sight. I cant seem to find anything to figure this out. Any help?

fortunately you can find numerous AI tutorials, what you need is patrol behavior.
