Armstrong was booked in the Harris County Jail, where U.S. Marshals said she will remain until she is transferred to Austin.
Deputy U.S. Marshal Brandon Filla told Nexstar’s KXAN that Armstrong was found with an altered appearance. Armstrong had shoulder-length hair that had been dyed dark brown, along with bandaging on her nose and bruising under her eyes after a reported surfboarding incident.
Photos from travelers at the airport show Armstrong back on U.S. soil. Armstrong is seen wearing a blue long sleeve shirt, black joggers and flip-flops. The photos also show the altered appearance previously referred to by officials.
Armstrong was arrested on Wednesday in Costa Rica and arrived Saturday afternoon in Texas. U.S. Marshals worked with Homeland Security and authorities in Costa Rica to find her at the hostel on Santa Teresa Beach.
Investigators said Armstrong, 34, used a phony passport on May 18 to board a United Airlines flight from Newark, New Jersey, to San Jose, Costa Rica, according to U.S. Marshals.
Armstrong faces charges related to the murder of world-class cyclist Moriah Wilson and unlawful flight to avoid prosecution.
