DENVER – A man who pleaded guilty to killing his wife was sentenced to 44 years in prison on Monday.Frank Schilt, who had faced a maximum sentence of 48 years, pleaded guilty in May to second-degree murder in the death of Teresa Schilt. Her body has never been found despite a three-month, $1 million search of two landfills in 2006.Authorities said Schilt told detectives he and his wife were arguing about money on Feb. 25, 2006, when he pushed her and she struck her head on the headboard of a bed.According to an arrest affidavit, he told detectives that he wrapped her body in a comforter and kept it in the trunk of his car for several days before wrapping it in plastic bags and putting it in a trash bin.Schilt disappeared a few weeks after Teresa Schilt was last seen. He was captured in Arkansas, where authorities said he was trying to hang himself.Schilt was originally charged with first-degree murder as well as attempted first-degree murder for allegedly poisoning his 15-year-old daughter with carbon monoxide. Authorities said he was trying to kill himself by carbon monoxide poisoning when both were home.Prosecutors dropped those charges in exchange for his guilty plea.Schilt has also been ordered to pay $5,000 in restitution to cover health care costs for his daughter, said district attorney’s spokeswoman Lynn Kimbrough.
