It took an Audrain County jury three hours of deliberations Wednesday to find Calvin Pettey guilty of murdering his fiancee.
Pettey was charged with shooting Sandra "Sandi" Michelle Fugate two days before their wedding.
Fugate's mother testified to the jury earlier this week about discovering her daughter's body in the basement of Fugate's Iowa Street home with several bullet wounds in her head.
According to court documents obtained by KHQA in 2010, Pettey admitted to killing his fiancee and asked others to help him dispose of the gun, ammunition and clothes he was wearing at the time.
Pettey and Fugate had been engaged for about a year at the time of her death.
The Hannibal Courier Post reports that a witness told police Pettey admitted he killed Fugate and asked for help in getting rid of the evidence. The witness also reported Pettey wanted the ammunition thrown in a body of water because they may have his fingerprints.
Fugate had a daughter from a previous marriage and was employed by General Mills in Hannibal. People who knew her say she loved spending time with family and friends.
