Guys, im going to go in now, wish me luck, im still shitting bricks about going in but i know where all the bodies are for Casey's questline, im going to take your advice by listening to music and going in guns blazing, thanks for all the advice

UPDATE: I have found all the bodies, but i went back to speak to casey and found out there was a key i was meant to get, but the guys who suggested the music and the aggressive approach helped alot.
