DENVER -- As police continue to wonder where his little girl's body is buried, Aaron Thompson wants to go back to court.

His lawyers filed their appeal of both his convictions and sentence Tuesday with the State Court of Appeals.

Thompson was convicted in Arapahoe County District Court in late September on 31 criminal counts surrounding the disappearance and death of his daughter Aarone.

She was reported missing to Aurora police on Nov. 14, 2005.

Thompson refused to say where she was buried and was sentenced on Nov. 10 to 114 years in prison for child abuse resulting in her death, as well as dozens of other charges related to the systematic abuse of the other surviving 7 children living in his East Kepner Place home.

Thompson's live-in girlfriend, Shely Lowe, died in May of 2006 of a heart attack, just as a grand jury was preparing to look into one of the metro area's most perplexing mysteries.

"I'm not surprised. They appeal everything," said senior prosecutor Bob Chappell with the Arapahoe County District Attorney's Office. "I don't think there's a reversible error in this record. Judge Spencer made complete and careful rulings. We'll just have to wait and see."

And, as with most things related to this case, the wait will be extensive.

"The record will be due from the trial court by April 1. Generally, an opening brief is due to the court 40 days after it receives the trial record, but the public defender can put a case on an automatic extension list to get more time," said John Sarche, Public Information Coordinator for the Colorado State Court Administrator's Office.
