The period of parole shall be the maximum of any sentence, less deductions for good conduct and work as provided by law, for which the paroled inmate, at the time of release, was subject to imprisonment under his or her definite or indeterminate sentence, as the case may be: Provided, That any time after a parolee has been on parole for a period of one year from the date of his or her release, a panel of the board may, when in its judgment the ends of parole have been attained and the best interests of the state and the parolee will be served thereby, release the parolee from further supervision and discharge him or her from parole: Provided, however, That no inmate sentenced to serve a life term of imprisonment and released on parole shall be discharged from supervision and parole in a period less than five years from the date of his or her release on parole.

No parolee who has violated the terms of his or her release on parole by confession to, or being convicted of, in any state of the United States, the District of Columbia or the territorial possessions of the United States, the crime of treason, murder, aggravated robbery, first degree sexual assault, second degree sexual assault, a sexual offense against a minor, incest or offenses with the same essential elements if known by other terms in other jurisdictions shall be discharged from parole. A parolee serving a sentence in any correctional facility of another state or the United States may, unless incarcerated for one of the above enumerated crimes, be discharged from parole while so serving his or her sentence in said correctional facility or be continued on parole or returned to West Virginia as a parole violator, in the discretion of the Parole Board.
