The Texas deputy who first flagged the license plate on suspected Las Vegas killer Anthony Wrobel’s vehicle outside a freeway rest stop last week is in his first year on the force, a fellow deputy said Thursday. When the Oldham County Sheriff’s Office rookie radioed K9 deputy Taner Blackburn, 34, for backup and to tell him the Utah plate came back stolen, Blackburn told him to stay back until he got there. Wrobel, 42, is suspected of opening fire at Sunset Park on two casino executives during a company picnic for employees of The Venetian on April 15. The arrest put an end to a days long nationwide manhunt that included investigators from several local and federal agencies.
