Serial Actual Outlook A Movie Based On A Serial Killer But Has Actual Footage In It?

A movie based on a serial killer but has actual footage in it? - serial actual outlook

I know it sounds a bit vague there, but at all times, "Diary of the Dead" was published (a year) actually two movies combined. It is a film about a serial killer, or perhaps in some others, it contains real photographs of a massacre there. I think he was a murderer that was what he was doing his record murders. I saw a preview on MySpace and it can not be found everywhere. I want to break your head, they found. Help? :)
