The FBI is trying to track down two men dubbed “Grandpa Bandits.”  Agents say one suspect is responsible for six stick-ups and the other is a suspect in 18 robberies across 12 states.  So far, “Grandpa Bandit” #1 has struck banks in Alabama, Arkansas, Florida, Georgia, Kansas, Michigan, Mississippi, Oklahoma, New York, Tennessee, Texas, and Virginia.  The FBI has had tremendous success with their digital billboards, and currently there are 75 of them displayed in those states looking for information.  “Grandpa Bandit” # 2 is on the run in Oregon, and his most recent robbery was last week at a branch in Medford.  The FBI says his previous five robberies were in Salem, Sherwood, West Linn, and Hillsboro.  In one instance, a teller told agents the suspect did show a weapon in his waistband, and did threaten to kill the teller.  Most of the incidents take 90 seconds or less.  According to a recent crime statistic report for 2009 released by the FBI, there were a total of 5,943 robberies of banks last year with more than $45 million taken from institutions, and the hours of 9 – 11 a.m. were the most popular times to strike.
