Every coroner who has weighed in agrees: The autopsies showed there was no stippling, tattooing or gunpowder residue at the wound in Jacob Limberios' head from the gunshot that killed him March 2, 2012.
"That is the key to solving this," Dr. Cyril Wecht tells Dr. Phil.
Wecht, and Dr. Michael Baden, another famed pathologist who looked at the autopsy and statements by witnesses, could testify as early as today at a special Sandusky County grand jury convened to review the Limberios killing.
Wecht, who Dr. Phil calls "the best of the best," said Jacob Limberios was the victim of homicide because the lack of gunpowder tattooing makes it extremely unlikely he shot himself.
Brittany Bowers and Will Lewis, who were with Jacob when he was killed, agreed to take lie detector tests on the program.
"If these two sat with Jack Dimarco and took a real and legitimate polygraph, with somebody doing the right thing in the right way, and pass that polygraph will you turn them loose and leave them alone? Will that solve this for you in your minds and hearts?" Dr. Phil asks Mike and Shannon Limberios, Jacob's parents.
Lie detector tests administered during the original investigation have been called unreliable and were conducted improperly, according to experts.
The results of the "Dr. Phil" show tests are to be revealed on today's program. Watch "Between the Lines Live" at 4 p.m. today from Village Pizza House West in Castalia with the Limberios family and Justice for Jake & Ella supporters as they view the second installment of the two-day "Dr. Phil" program.
