After being on the run for 43 days, fleeing murder charges, Kaitlin Armstrong has been arrested in Costa Rica, U.S. Marshals announced in a statement released Thursday.
A joint effort between the Marshals, Homeland Security Investigations, and the Department of State Diplomatic Security Service found Armstrong in a hostel on Saint Teresa Beach in Provincia de Puntarenas, the statement says.
Armstrong will be deported back to the U.S. to face charges of first-degree murder and unlawful flight to avoid prosecution, the statement says.
Marshals and Homeland Security say she boarded United Airlines Flight 1222 using a fraudulent passport via Newark International Airport at 5:09 p.m. EST on May 18, according to the statement. She arrived in San Jose, Costa Rica at 8:27 p.m. EST, the statement says.
“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, in the statement.
Armstrong, 34-years-old, is charged with the first-degree murder of 25-year-old pro-cyclist Mo Wilson after a May 11 shooting that left Wilson dead in her friend’s residence in Austin, Texas, according to the affidavit released in May.
In what is being deemed a love triangle gone wrong, Wilson and Armstrong had both been romantically involved with professional cyclist, 35-year-old Colin Strickland, the affidavit states. Strickland and Wilson dated briefly in October 2021, while he and Armstrong had broken up, though the relationship ended and Strickland went back to Armstrong, the affidavit says.
Strickland has been cleared as a suspect, Austin police said in May.
“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,” Pamerleau added in the statement.
