Terrance Black was wanted in connection with a possible Texas murder of his ex-girlfriend. When police spotted him, he took off running, and jumped off the south rim. He fell 25 feet. He survived and is recovering in the Flagstaff Medical Center… under police security.
Black had an arrest warrant out for him. So police were permitted to arrest him as soon as they spotted him and confirmed it was him. When Black took off running, they chased. Black’s flight from the police could be a separate felony charge here in Arizona (in federal court because it was in the Grand Canyon National Park).
Flight can also be used as evidence of guilt, if this case proceeded to trial. Flight from police is never a good idea because it can be a crime and it will be used against you in your criminal case as evidence of guilt
