A 22-year-old Natchitoches man was killed this morning when he ran into the rear of a loaded log truck -- on private property -- at the International Paper Company mill in Desoto Parish.Trooper Cordell Williams says investigators have determined that the log truck was slowing to make a left turn and that it's tail lights were not working at the time. However, Williams says the log truck's driver cannot be issued a citation for that violation because it occurred on private property. The victim's name has not been released.
