A psychiatrist ruled that Carly Gregg cannot use the insanity defense in the trial for the murder of her mother due to the ‘diabolical’ nature of her actions. Gregg, 31, is accused of killing her mother, 58-year-old Linda Gregg, in their home in Pennsylvania in 2020. The psychiatrist determined that Gregg’s actions were premeditated and showed a level of planning and control that contradicts the insanity defense.
