Blackwelder said the intensity of the police work necessary to bring the Shaffer case to trial has been difficult on his deputies and staff.
"Unfortunately we have the distinction of having two multiple homicides and it takes a huge toll on the personnel," he said. "It takes a toll on their personal lives and it takes a toll on the resources that we have."
He said the investigators are working just as diligently as they did three years again to solve the latest killings. And he tried to assure residents that they shouldn't be afraid.
"I don't feel like the residents of Lincoln or Madison counties, either one, should be concerned with their safety, because this was not a random act," he said.
