A white supremacist Idaho prison gang member and an accomplice remained on the loose Wednesday after the accomplice staged a brazen overnight attack to free the inmate as he was being transported from a Boise hospital, police said.
Police identified the man suspected of shooting two corrections officers during the ambush as Nicholas Umphenour. A warrant with a $2 million bond has been issued for his arrest on two charges of aggravated battery against law enforcement and one charge of aiding and abetting an escape, police said.
