A San Carlos woman fatally stabbed her boyfriend's pet bearded dragon in cold blood, the first act of a drama that ended with her in jail for trying to grab a sheriff's deputy's gun, authorities say. Shawna Apour, 37, killed the lizard because she thought her boyfriend was flirting with other women, said San Mateo County District Attorney Steve Wagstaffe. The victim was Speedy, a 14-year-old bearded dragon, said sheriff's Lt. Ray Lunny. Speedy clung to life for three days before dying.
