A 23-year-old Anaheim woman who fled to Mexico after she allegedly decapitated her 55-year-old boyfriend last year was extradited back to Orange County, authorities said. Ashley Marie Lira will make her first court appearance in Fullerton on Feb. 13, when she may enter a plea, said Kimberly Edds, an Orange County District Attorney’s Office spokeswoman. Lira, who had dated Gonzalez-Carbajal for two months, was identified as a suspect, Edds said, with officers learning she immediately fled to Mexico after the slaying. For five months, Orange County, Mexican and FBI authorities worked to find and arrest her. On Jan. 22, she was taken into custody by Mexican authorities, Edds said, and the next day Anaheim detectives picked her up at the San Ysidro border crossing.
