A woman who is suspected of playing a role in a fatal shooting in Oceanside three years ago was arrested in Tijuana and returned to the U.S., authorities said. Baja California officials said they arrested on Tuesday a woman they identified partially as Aarin Marie, a 50-year-old Canadian citizen. Marshals officials said in a news release that Mexican authorities transferred Sorenson into their custody at the San Ysidro Port of Entry. The area was so large that it took nearly two weeks to locate Sanders’ body after the shooting was reported. Three people were arrested in the weeks following the shooting, but Sorenson remained at large until she was arrested this week.
