appeared to be stalking sherry, yet sherry never mentioned the woman's name to her parents. instead, she told them not to worry. >> she told me, i want to see if i can't work this out myself. >> that conversation happened during a dinner celebrating sherry's 29th birthday. after ward her parents took sherry to the airport. >> as she walked away she turned and gave me a big smile and i've relived that smile for years. >> less than three weeks later, sherry laid dead. they insist that early in the investigation they told the lead lapd detective about sherry's troubling encounters with john's ex- girlfriend. >> i told the detective, not once, but probably 15 to 20 times and he said, the trouble with you is you've been watching too much tv.
