"From what we determined, at the time, he believed she was still breathing and had some movement at the time she was going into the freezer,"
Police said that they believe that Cumming was injured in December after a fall, and that Tincher didn't seek medical attention for his grandmother, instead dragging her through the home.
A warrant for Tincher's arrest states that he "heard and saw numerous bones break." He wrapped Cumming in plastic bags and placed her in a large freezer, according to police.
Charges state that Tincher "acknowledged her back broke going into the freezer."
He also told the investigator how much he loved his grandmother.
"He said she was the only family member that gave him the courtesy and love and attention he needed," Werner said.
