>> to tom and dar's close friends, the pierces, news of tom's arrest was almost as stunning as the news of dar's death. could you conceive of tom either hating his wife so much that he wanted to kill her -- >> absolutely not. >> -- or killing her for the insurance money? >> absolutely not. >> that would be stupid. she made the money. why kill the golden goose? >> do you think they had a good marriage? >> i do. everything seemed to be going really good for them. >> it seemed sadistic, shooting your wife at point-blank range, killing the mother of your son on the very day he was celebrating his tenth birthday. >> he never would have done that to his son. >> police continued gathering evidence. ten days after tom's arrest, police brought heath foley in for a second interview. and this time heath did recall hearing a noise that day.
