Lead investigator talks about Cheryl Durkin murder case

Anthony Dwyer, now chief deputy of the Butler County Sheriff’s Office, was the lead detective on the case. When Durkin's torso was found on the bank of the Great Miami River, Dwyer didn't have much to go on. But science and technology helped along the way. . Prosecutors said Lawson killed Cheryl in his house on Garfield Street in Middletown. He hit her at least four times in the head with a hammer, then he dragged her downstairs and stuffed her through a hole into the basement. Then he used a power saw to cut her apart. Peck helped dispose of Cheryl's body parts in separate graves near Rush Run Wildlife Area in Preble County and Brookville Lake, Indiana.
