Buell Wesley Frazier and his interrogation by Will Fritz
Hang on a minute. You claimed;
People say a lot of things. Especially a person who drove the eventual prime suspect to the eventual murder scene. And was the person who apparently underwent a lengthy interrogation in which he was threatened with fisticuffs unless he 'fessed up.
The video shows that Fritz presented Frazier with a written confession to sign early on and got angry when Frazier stood up to him and refused to sign it.
Only after Fritz left (and Frazier said he never saw him again) was Frazier being interrogated for hours!
What I don't understand and you likely can not explain is why would Frazier feel so intimidated during the later interrogation that he lied about the bag, when he had already shown no sign of being intimidated by Fritz?
