Killer doctor's son played key role in his demise as he recalls haunting sounds decades later

It was five days after Christmas in 1989 that Collier Landry heard what he said sounded like "a body hitting a wall."

It was late at night, and the 11-year-old was in bed, not knowing that his mother, Noreen Boyle, was being murdered in their Ohio home.

"I will never forget those sounds – they haunt me," the now-46-year-old told Fox News Digital. "But there was nothing I could have done to prevent what may have been occurring."
