At the end of an eight-day trial, a Richland County jury deliberated three hours and found 28-year-old Marcus Bailey guilty of killing 26-year-old Almanita Smith and putting her body on the front lawn of their home last August.
The defense made the case that someone else came along and dumped Smith's body at the home on Heron Glen Road.
But prosecutors said Bailey's statement to investigators that he had seen Smith just the day before her body was found was a lie because the body was badly decomposed.
Prosecutors presented evidence that Bailey murdered the Columbia College graduate and former staff sergeant in the military, then wrapped her body in a blanket and stored it in the northeast Richland County home.
They alleged he used air fresheners to cover the odor, and only placed the body outside because he learned there might be a search of the residence.
Investigators say Smith's death was a tragic case of domestic violence, and Fifth Circuit Solicitor Dan Johnson said in a statement that the verdict sends a clear message that such brutal and heinous acts won't be tolerated in the community.
Bailey was sentenced to 50 years in prison.
