this was my mom, a vibrant, healthy woman who was just ripped out of the world. >> what happened? michele was a young 50, didn't drink, didn't smoke. she was carrying more weight than she wanted to but the only thing out of the ordinary was the surgery she had just had. >> i wasn't concerned about the health aspect of her doing the facelift. i just didn't think she needed it. >> so, if a complication from the surgery seemed unlikely, perhaps this theory from martin made more sense. maybe michele had taken too much pain medication and while running a bath fell headfirst into the tub. >> he said she was slumped over the tub. her head down into the water and her legs out of the water. >> but something about that didn't sound right to alexis. for one thing, 6-year-old ada who also saw her mother in the tub had a slightly different memory. >> she said that she saw her laying back, her head by the faucet. >> facing up?
