They are working on fresh information gleaned from Ream himself, as well as some others, and believe that the missing girls could be buried in the same area. Police suspect that Ream could be behind her mysterious disappearance in the area where her grandparents lived. He later failed a lie-detector test, Dwyer said.
They are specifically seeking the remains of Kimberly King, last seen in 1979 at age 12, but Dwyer said Ream reportedly boasted to fellow inmates that he had killed several other girls.
The police commissioner in nearby Warren appealed to the inmate to help investigators find the remains. Even though other detectives were suspicious of Ream, they continued to treat Cindy's case as that of a runaway, because a body was never found. "No question about it, that Kimberly King and other young female victims who were murdered are buried here".
On Monday, after gaining a search warrant, a team from the Warren Police Department, the Macomb County Sheriff's Office and the Federal Bureau of Investigation returned to the site with the equipment necessary to do a major dig.
"I pray for him every day that his heart softens", Edward Zarzycki said Wednesday at the excavation site.
Officials have not announced any findings.
According to dates listed on the Michigan Department of Corrections website, in August of 1975, Ream was sentenced to between five and 10 years in prison for that conviction. Her body was finally found in 2008, 22 years after she was last seen.
The 7 Investigators are uncovering new details about Arthur Ream's past.

"It would mean a great deal to be able to bring her remains home", Beyma said. O'Dell, who was walking to her boyfriend's home in Taylor to babysit and never made it on August 16, 1974; and Cynthia Coon, who vanished on April 1, 1970 while walking to school in Ann Arbor. "He came to the house and he was like 'Where's Nadine?' She wasn't there and that is how it all started".
When asked about the search for bodies, Police Commissioner Dwyer did have the following to say.
"I just remember her as a very quiet person". Brenda Lee Handloser, who was 9 when her sister, Nadine O'Dell, vanished, told CNN affiliate WDIV that closure is all she wants. "My father is 80 years old".
