A Texas woman suspected in the fatal shooting of professional cyclist Anna Moriah Wilson at an Austin home has been arrested in Costa Rica, the U.S. Marshals Service said Thursday. Kaitlin Marie Armstrong, 34, was arrested Wednesday at a hostel on Santa Teresa Beach, the Marshals Service said in a statement. Armstrong was expected to be returned to the United States, where she faces a murder charge, the agency said. Wilson, 25, was found dead May 11, and Austin police later issued a murder warrant for Armstrong.
