Gannon University Associate Professor Jerry Clark spent 27 years in Law Enforcement and he's weighing in on the Michael Burham escape from prison.

He was the lead FBI Investigator in the "Collar Bomb" or Pizza Bomber Case and wrote a book about his experience.

He also wrote a book entitled, "On the Lam", A History of Hunting Fugitives in America."

When Clark heard about the escape from the Warren County Jail, his old FBI instincts kicked in.

Clark says setting up a wide web early in the process, is critical to the search.
