An Ohio plan has pleaded guilty to using a destructive device during and in relation to a crime of violence and possessing a destructive device in furtherance of a crime of violence.

58-year old Keth Seppi was in U.S. District Court in Syracuse today, where he admitted that he built a bomb and delivered it to corrections officer Alan Dorbansky's Floyd home last May.

Dorbansky was seriously injured when the package exploded.

Seppi, his wife and his wife's sister, Donna Seppi and Cindy Sields, were all charged in the case.

Authorities say Shields had been working as the caretaker for Dobransky’s mother in Ohio for four years and allegedly stole money from her.  They say Dobransky had planned to make a report to law enforcement in Ohio.

Seppi faces at least 30 years and up to life in prison when he's sentenced on July 5th.
