The first case I remember seeing was about a woman who worked as a horse hand, I think. She had a jealous ex boyfriend or husband, she started dating someone else, they came home from a rodeo one night to the woman's trailer and the next day they were both missing?
Anyone know what this is?

Yes I remember that one. The woman's name was Melissa Jo Sermons and the man was Larry Costine. She did have a jealous ex-boyfriend and they did go to Larry's house late one night after a rodeo. Larry's body was found in his trailer a few days later and he had been shot to death. Melissa is still missing. Apparently there have been no arrests in the case:

Hey, that sounds interesting. Do you have room on the Vol. 5 for that one, CD?
