Upwards of 1,000 law
Upwards of 1,000 law enforcement officials have been involved in the search for Frein, named last week to the FBI's 10 most wanted list. He is considered armed and dangerous, and police have authority to kill him if he doesn't surrender.
In an indication of just how wild the landscape is, tactical teams have "kicked out quite a few bears" as they search for Frein in caves, Bivens said.
