Jurors last week were shown chilling photos of Lunsford’s body, found in two knotted black plastic bags buried in a shallow hole.
Prosecutor Ric Ridgway also unveiled a mattress belonging to Couey that they say is stained with Lunsford's blood. The mattress was found in a trailer about 150 yards from the Lunsford home in Homosassa.
The girl's fingerprints also were found on a glass tabletop and on cardboard in a closet in the trailer, Ridgway said.
Couey, 48, is a convicted sex offender. He's accused of sneaking into the Lunsford home where he allegedly abducted Jessica, raped her and later killed her by burying her in garbage bags while she was still alive.
Two of the girl's fingers poked through the plastic and she was clutching a stuffed purple dolphin her father had recently won at a fair.
Couey has pleaded not guilty. He could get the death penalty if convicted. Defense attorneys say he was coerced into making incriminating statements.
Couey spent much of his time at the defense table during jury selection working diligently on a dinosaur coloring book with a pack of colored pencils.
John Couey is charged with first-degree murder, kidnapping, sexual battery on a child younger than 12 and burglary. He faces the death penalty if convicted.
