Documentarian remembers Frein as an 'oddball'

Just hours after police captured accused cop killer Eric Matthew Frein, Thursday evening saw Anderson Cooper welcome Patrick Bresnan in search of firsthand insight and perspective.

A documentarian, Bresnan worked with Frein on the film "Vietnam Appreciation Day," and vividly remembers the former fugitive as being an arrogant outlier:

"He definitely struck me as an oddball," Bresnan told Cooper. "He saw his brand of military understanding, or military reenactment, as being much more refined."

Watch the above video for more of Bresnan's assessment and analysis of the man who had been considered to be a Top Ten Fugitive by the FBI.
