U.S. marshals announce arrest of Texas cyclist suspected of murdering female rival Anna Moriah Wilson

A Texas cyclist accused of murdering another woman has been apprehended at a Costa Rican resort and will be extradited to the U.S., authorities said on Thursday. 

Kaitlin Armstrong, who is wanted in connection with the May 11 murder of Anna Moriah Wilson in Austin, was arrested "at a hostel on Santa Teresa Beach in Provincia de Puntarenas," the U.S. Marshals said in a press release.

Armstrong reportedly fled the country under a fraudulent passport; police said they could find no outbound flights under her name at Newark Liberty International Airport where she was last seen. 

“The Marshals Service elevated the Kaitlin Armstrong investigation to major case status early in this investigation, which likely played a key role in her capture after a 43-day run,” U.S. Marshal for the Western District of Texas Susan Pamerleau said in the department's press release.

“This is an example of combining the resources of local, state, federal and international authorities to apprehend a violent fugitive, bring an end to that run and hopefully a sense of closure to the victim’s family," she added. 

Armstrong "will be deported and returned to the U.S.," the Marshal service said.
