Thursday morning, the U.S. Marshalls announced that Kaitlin Armstrong, the woman suspected of killing her boyfriend’s lover, was arrested in Costa Rica.
Armstrong allegedly used a fake passport to leave the country. She was hiding at a Santa Teresa Beach hostel in Provincia de Puntarenas, Costa Rica.
In a statement, the U.S. Marshalls said Armstrong boarded a flight on May 18th from Newark International Airport. She used fraudulent documents to travel outside the US.
“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,” said U.S. Marshal for the Western District of Texas Susan Pamerleau. “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.”



Kaitlin Armstrong sparked an international manhunt after law enforcement issued an arrest warrant for her arrest in connection with the murder of pro-cyclist Mo Wilson.
Wilson was romantically involved with Armstrong’s boyfriend. On the night of May 11th, police responded to a call to an East Austin, TX residence. Upon arrival, officers discovered the victim, Mo Wilson, dead from multiple gun shots.
A video surveillance caught Kaitlin Armstrong near the East Austin residence. She was picked up by police and arrested on an outstanding warrant. However, the police had to let her go on a technical error. She skipped town, driving a stolen car.
Several days later, police reported sightings of Armstrong at LaGuardia Airport, but her name was not found on any flight lists.
Armstrong has been extradited back to the U.S.
