As a young boy, 11-year-old Collier Landry heard his father murder his mother in the dead of night. The only witnesses were Collier and his little sister, who claimed she saw, “Daddy hit Mommy and wrap her up like a snowman.” Their father, Dr. John Boyle’s, murder trial was the trial of the decade — a pregnant mistress, a secret house, a body buried under the floorboards, and a key witness, Collier, who faced his father and helped put him behind bars. Now, more than two decades after the notorious murder, Collier is confronting his father to get answers about his mother’s death. Collier speaks out in an exclusive interview.
