TUCSON, Ariz. (AP) -- A man walking his dog has found a black bag holding ammunition that authorities believe was discarded by a gunman accused of trying to assassinate an Arizona congresswoman.
Chief Rick Kastigar with the Pima County Sheriff's Office told The Associated Press that an 18-year-old found the bag Thursday morning in a neighborhood near where the suspect lives. He went to get another man, who looked inside and saw ammunition.
Authorities have said the suspect, Jared Loughner, and his father got into a confrontation over the bag at their home in the hours before the shooting.
