Anna Walthall took the witness stand and said she began a six-month affair with MacNeill in when he was a consulting doctor at a laser hair removal clinic that she operated.
Walthall quoted MacNeill as saying, "'There's something you can give someone that's natural that's a heart attack that's not detectable after they have a heart attack. No cause of death has been determined for MacNeill's wife, Michele MacNeill, who was found dead in her bathtub in April Defense lawyers have argued that she had a heart attack and fell into a tub in the family home in Pleasant Grove, about 35 miles south of Salt Lake City. Defense lawyers challenged Walthall by getting her to acknowledge she had been diagnosed with what was formerly called multiple personality disorder, but she insisted she was giving a true account of Martin MacNeill's statement.
Earlier in the day, two of MacNeill's daughters testified that their father had hired another mistress, Gypsy Willis, as a nanny soon after his wife died, but Willis did not cook or take care of the children and went to their father's bedroom at night.
Willis earlier testified that she and Martin MacNeill had a sexual relationship. Another daughter, Alexis Somers, testified that Willis would come and go throughout the day, seemingly more focused on the doctor than the children.
Prosecutors say Martin MacNeill, 57, hounded his wife, Michele MacNeill, to get cosmetic surgery then knocked her out with painkillers and left her to die in a bathtub. His motive, they said, was to get rid of his wife so he could be with Willis. Somers testified that her father bullied her mother to get the face-lift and insisted the plastic surgeon prescribe an unusual combination of painkillers and other drugs for her recovery.
