Well, this bit of info is not helpful for the prosecution IMO:
"Judge Derek Pullan said Monday that Dr. Martin MacNeills 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."
