Passerby: "Something was wrong that night"
In May 1995, Harold Henthorn and his first wife, Lynn, stopped on a remote highway to change a tire. According to Harold, Lynn reached under the car to get a lug nut when their Jeep fell off the jack, crushing her. Patricia Montoya and her family stopped to help. She talks with "48 Hours" about what she remembers from that tragic night.
