A man has been busted in the murder of a US Airways flight attendant who was found naked, bound, and strangled in a Mexico City hotel. FBI agents nabbed the suspected killer of Nick Aaronson using a hotel surveillance camera and tracking the GPS on his stolen cell phone, reports KPHO TV in Phoenix. "I wish they had the death penalty in Mexico," Aaronson's mom said. The killer "took the light out of my life," she added. Aaronson was in Mexico during a work layover and his body was found by co-workers. His luggage was strewn about and cash was missing, according to authorities. He apparently met his 20-year-old killer in a local bar before Aaronson returned to the hotel with him. The suspect has admitted punching Aaronson, but denies that he killed him.
