It was the perfect crime, except for the part where Malcolm Thomas tripped on his way out of the gas station he had just robbed while running with the register tray. A witness saw him fall, and when police searched the spot, the Southwest Times Record details what they found: "a large amount of change, a pack of condoms, and Thomas’ state-issued identification card." It was that last one that did him in, and the 21-year-old got sentenced to 12 years in prison yesterday in Sebastian County Circuit Court in Arkansas. It did not help his case that when police were tracking him down, his cousin asked, "Who did he rob this time?" (Click to read about how vanity led to the arrest of an Ohio woman accused of robbery.)
