ORLANDO , Florida ( CNN ) -- There was no trauma visible on the `` completely skeletonized '' remains of slain toddler Caylee Anthony , but there were overlapping pieces of duct tape over her mouth , according to the autopsy report released Friday . Caylee Anthony was last seen June 16 , 2008 . Her mother , Casey Anthony , is in jail awaiting a murder trial . The tape was still attached to head hair , and the skull was separate from the other body parts , said Dr. Jan Garavaglia , chief medical examiner for Orange County . `` This duct tape was clearly placed prior to decomposition , keeping the mandible in place , '' she says in the report . Garavaglia said animals had scattered the bones after decomposition began . The cause of the child 's death is listed as `` homicide by undetermined means . '' Caylee Anthony 's remains were found in December in woods less than a mile from her grandparents ' home . Her mother , Casey Anthony , is charged with murder . She could be sentenced to death if convicted . The mother was arrested July 16 , 2008 , while Caylee was still missing . Earlier Friday , a judge denied a request from the child 's grandparents , George and Cindy Anthony , to keep the autopsy report from the public . Last week , their attorney filed a motion saying the report should be sealed because its release would cause the family great anguish . Holding back tears , George Anthony on Friday asked the judge not to release the report until Casey Anthony 's trial . `` Our family 's memory of precious Caylee Marie is all we have left of her , '' he said as his wife appeared visibly shaken . Judge Stan Strickland said George Anthony 's testimony was not lost on him , but according to the law he had no choice . `` Their pain means a great deal to me . I do n't like the ruling I 'm making , but it 's one that I legally have to make , '' he said . George Anthony , angry after the ruling , left the courtroom before the hearing ended . The autopsy report contains no X-rays or photos of the remains . Watch Nancy Grace 's take on the coroner 's findings » . According to Garavaglia , intermixed with Caylee Anthony 's skeletal remains were two plastic garbage bags , a canvas laundry bag and a baby blanket with a Winnie the Pooh print . A pair of partially decomposed , multi-colored shorts were among the clothes , the doctor said . Two sets of cloth letters were found intermingled with plant material and debris . Garavaglia said the first set spelled `` big '' and the second group appeared to spell `` trouble . '' `` The roots growing into the vertebrae and bags indicate the body was placed there months prior to being found , '' Garavaglia said . `` There is nothing inconsistent with the body being placed there soon after the date of [ Caylee ] being last seen alive . '' George Anthony said he saw his granddaughter leave his house with her mother for the last time on June 15 , 2008 . Officials allege Caylee was killed by her mother a short time later . Since her arrest in July , Casey Anthony , 23 , has remained behind bars in Orlando . The search for Caylee ended December 11 , when a meter reader brought out a bag containing a skull from the woods . He said he had contacted police three times in August to report a suspicious bag in the area . A deputy was ultimately fired for not properly searching the area . The remains were confirmed through DNA testing to be those of Caylee Anthony . CNN 's Natisha Lance and John Couwels contributed to this report .
