Late 80's early 90's movie about a group of hikers setting of on regular walk only to be killed 1 by 1 during the hike . The killer is not known to any of the others and is a bit of a whodunnit type movie .you are not sure who or why he is killing people . The main character is the one who eventually stops him but for the life of me cannot get the movie or actors names . Plese help
