VAIL, Iowa (AP) – Authorities in Crawford County are looking for a suspect who they say threatened a teller at the Westside State Bank in Vail with an explosive device before fleeing with an undisclosed amount of cash. The robbery occurred just after 9 a.m. Saturday. Crawford County Sheriff Jim Steinkuehler said the man, described as white, in his 30s or 40s with a red goatee, threatened a teller with a Molotov cocktail but did not use the homemade bomb. The sheriff says the suspect, who was also wearing sunglasses, took an undisclosed amount of cash and fled on foot.  Bank President Matt Lujano declined comment.
