The latest criminal cases against Viola homicide suspect William White will move forward. Probable cause has been found to hold him over for trial in separate Class 3 felonies of threatening a public official and driving while license revoked–both charges filed last December. Pre-trial conferences have been scheduled for March 4th. The threatening a public official count accuses White of making threats against Mercer County Public Defender Dan Dalton. And White also has 13 prior driving while revoked convictions. Both new charges are extendable by up to 10-years in prison upon conviction. White has been deemed “a person of interest” in the death of his estranged wife, 39 year old Melissa White, but has not been charged in the case. She died of skull fractures at her Viola home in October of 2011. William White was sentenced to four-years in prison in January of 2012 on a felony driving while revoked conviction, a charge unrelated to the homicide investigation. He is now in custody at the Mercer County Jail on $150,000 bond.
