Police said Matthew Puccio, 25, of Urbana, Ohio, was charged with murder, abuse of a corpse and related charges in the death of Jessica Rae Sacco, 21, also of Urbana.
The other suspects -- Andrew Forney, 26, and Kandis Forney, 25, both of Fenton, Mich.; and Christopher Wright, 37, and Sharon Cook, 25, both of Urbana -- face various counts related to the dismemberment and disposal of the body, and obstruction of justice, WHIO-TV, Dayton, Ohio, reported.
All five were being held on bond following their arrests Saturday. Puccio and the Forneys are to appear in court in Hamilton, Ohio, Monday, while Wright and Cook are to have a court hearing in Urbana the same day.
Police said they believe Sacco was killed sometime around March 22, and that two days later the suspects took some of her remains to Hamilton and then to Covington, Ky., where they disposed of them.
WKRC-TV, Cincinnati, reported police allege Puccio stabbed and suffocated Sacco in her apartment and cut up her body with Andrew Forney's help. The other three suspects, who allegedly were in the apartment when Sacco was killed, are accused of doing nothing to stop it and then helping to cover up the homicide.
Police said they found some of her body parts off Hands Pike in Covington.
No motive for the killing was reported.
