Plenty of questions still remain two days after authorities discovered a dead body in the wheel well of a United Airlines aircraft in Hawaii.

Hawaii authorities are investigating a dead body found in the wheel well of a United Airlines plane that flew from Chicago to Maui on Christmas Eve. Newsweek has contacted United Airlines, Boeing, and the Maui Police Department for further comment via email outside of normal office hours.

The body was found in the wheel well of United Flight 202, which departed Chicago’s O’Hare Airport around 9:30 a.m. Tuesday and landed at about 2:15 p.m. at Kahului Airport in Maui.
