A jury has found a Utah doctor guilty of murder in the death of his heavily drugged wife in a bathtub.
Prosecutors argued Martin MacNeill knocked out Michele MacNeill with drugs after cosmetic surgery, then helped her into the tub and held her head underwater.
One man who served time with the doctor said MacNeill acknowledged doing that in 2007. The three-week trial featured a mistress whom prosecutors argued was MacNeill's motive for getting rid of his wife.
Gypsy Willis has testified that she had a 15-month affair with the doctor at the time of Michele MacNeill's death and that she was hired as a nanny and given a marriage proposal shortly afterward. But Willis said she ended the affair years ago, and she doesn't know anything about the death.
The jury found him guilty of murder and obstruction of justice.
