“He admitted he was the person responsible,” Shoudel told the courtroom.

But Duke’s attorneys said that he was under the influence of drugs and gave a false confession. Attorney Ashleigh Merchant argued that prosecutors had little evidence that Duke killed Grinstead.

“All they’ve got is an inconsistent statement from someone who was under the influence of drugs,” Merchant said.

Instead, it was Dukes who killed Grinstead, according to Duke’s defense attorneys. Duke only helped burn Grinstead’s body, his attorneys said.

But in a videotaped confession and a written statement to the GBI, Duke gave explicit details about his actions.

“Words are useless, but I’m burdened with the murder of Miss Grinstead,” Duke wrote in his confession, which was read in court.

Duke told the GBI he broke into Grinstead’s house to steal money to support his drug habit. But when Grinstead approached him, Duke said he struck her, killing her. Duke then left the home and later returned with a quilt and latex glove.

A glove was later found in Grinstead’s yard and sent to the GBI crime lab for fingerprint and DNA testing, Shoudel said. DNA from Grinstead and Duke was found on the glove, the agent said.

Duke’s attorneys contend he didn’t kill Grinstead, but only helped conceal her body.

“We’ve got the wrong person in custody judge, it’s the wrong person,” Merchant said.

The hearing is expected to continue Tuesday morning, when additional motions will be discussed.
