When David Harmon was bludgeoned to death in his bed 22 years ago, his wife, Melinda, claimed that two intruders had beaten him up looking for the keys to the bank where he worked in Olathe, KS. She claimed the intruders also hit her, and when she came to an hour later, her husband was dead. Police soon found holes in the story and began to suspect she might know more. But they were unable to re-interview her, and with few additional leads, the case went cold. Twenty years later, Olathe police decided to re-open their coldest murder case, reports Jim Avila. They traveled to Delaware, OH, where the remarried Melinda Raisch lived, and asked her again what happened that night. To their surprise, Raisch, now a suburban mother, told a slightly different story - still maintaining her innocence, but implicating her dead husband's best friend. Both were charged with murder, and this week Raisch learned the jury's surprising verdict in her case. "Primetime Live" airs THURSDAY, MAY 5 (10:00-11:00 p.m., ET) on the ABC Television Network.

Also: They're called "cougars," older, successful women - often over forty - on the prowl for younger men to date. Cynthia McFadden interviews actress Fran Drescher and model Jerry Hall, a couple of famous women who've very publicly dated men several years their junior. They weigh in on why what was once a "Mrs. Robinson" taboo has become so mainstream. And McFadden talks with a couple of male "cougar hunters" about why the allure of these older women is so irresistible.

And: Susan Robinson is a 45-year-old social worker who was suffering from low self-esteem when she was picked to receive a free "ultimate makeover" by a Florida plastic surgery center a year ago. "Primetime" followed her remarkable transformation. But what seemed like a Cinderella story apparently has come at a steep price. John Quiqones reports that Robinson's husband now believes his wife is not the woman he married -- either inside or out.

DIANE SAWYER, CHRIS CUOMO, CYNTHIA McFADDEN and JOHN QUIQONES are the anchors of "Primetime Live." DAVID SLOAN is the executive producer.
