A Utah judge ruled Monday to limit what could be some of the most damaging testimony facing a doctor accused of killing his wife as she recovered from a face-lift.

Judge Derek Pullan said Monday that Dr. Martin MacNeill’s daughter, Alexis Somers, will not be able to testify about some fears her mother Michele MacNeill allegedly divulged to her before she died. According to prosecutors, Michele MacNeill allegedly told Somers, "If anything happens to me, make sure it wasn't your dad."
Pullan also ruled that defense attorneys can impeach Somers’ character with evidence that they say shows she committed academic misconduct during graduate school.
Somers is still expected to testify about her father’s alleged suspicious behavior leading up to her mother’s death, and his interactions with a woman named Gypsy Willis whom he was allegedly having an extramarital affair with.

Prosecutors say Martin MacNeill was motivated to kill his wife because of his affair with Willis, and that he used his medical knowledge to do so.
Michele MacNeill was found dead in the family's Pleasant Grove, Utah, home on April 11, 2007, a few days after she got a face-lift. Medical examiners discovered a powerful cocktail of drugs -- including Valium, Percocet, Phenergan and Ambien -- in her system.
Martin MacNeill's trial is scheduled to begin October 15. He has pleaded not guilty to charges of first-degree murder and obstruction of justice. If convicted, he faces life in prison.
