there was no harm-no foul. they could politely tell me i was wrong and thank you for my help and i would go away. >> christine's urgent request to check yaz made it to the desk of this detective. gary mckee of the highland heights police department was already investigating rosie's car accident. >> i never had met christine. i didn't know if she had an ax to grind with him. whatever reason she didn't care for him may not have been a valid reason. so i wasn't approaching him as a suspect or even thinking that, you know, this guy's a murderer. >> still, the detective had some facts that didn't add up. 38-year-old woman in good health suddenly dead in a fender bender. what's more, the coroner couldn't give him a cause of death. at minimum, he had to find out more about those calcium capsules christine had told him about. you're wondering if there's a sad but benign reason for her death. is this tainted stuff or is she allergic to whatever was in it. >> exactly. i didn't know exactly what i had.
