New details have emerged following the capture of Kaitlin Armstrong, who is now formally charged with first-degree murder in the death of cyclist Moriah Wilson. Deputy U.S. Marshal Brandon Filla said that Armstrong used multiple aliases while on the run but confessed to her true identity, partly due to exhaustion, after a 43-day fugitive hunt ended when she was captured and arrested by foreign officials in Costa Rica.

"I'd say she was exhausted. You could tell eventually when she was encountered by uniformed officers in Costa Rica. She didn't give her true identity at first, but when she was taken into custody and questioned, you know, minutes later, she finally confessed to her true identity," Filla said in a press conference on Thursday at the United States Federal Courthouse in Austin.
