Jurors didn't get to hear that argument in detail because a federal judge said the doctor's 18-year-old daughter couldn't testify about why her father claimed he sent the photo.
U.S. District Judge Brian Miller said Dr. Randeep Mann must testify about that himself -- something that seemed unlikely as the trial entered its fifth week.
Prosecutors claim Mann planned the February 2009 bombing at Dr. Trent Pierce's home in retaliation after the Arkansas State Medical Board revoked Mann's right to prescribe narcotics.
