The Urbana man accused of stabbing, suffocating and dismembering his girlfriend has pleaded guilty to multiple charges. 26-year-old Matthew Puccio will be sentenced next month in the March death of 21-year-old Jessica Sacco. Her remains were found in the bathtub of their Urbana apartment a week after police believe she was killed. A Michigan couple and two other Urbana residents have pleaded not guilty in the case. Investigators say those suspects failed to intervene and helped Puccio dispose of the body parts in southern Ohio and Kentucky.
