Do i have enough evidence in heavy rain at the end?

i got through it last night but was a little disapointed when i was looking through the evidence when i was Norman jayden and he started bleeding from his eyes and died! i had the video from the fight car and hi gas station tickets and the tires of his car and i thought i got most of it. And also does that ler guy mean not to over indulge in ARI or tripto?
