Jacksboro, Campbell County (WVLT) - Kenneth Bartley Jr.'s new attorney has taken the next step toward withdrawing his client's guilty plea.

Bruce Poston has amended a motion filed by Bartley's old attorney explaining why the plea should be withdrawn.

Included in the motion, arguments made previously that Bartley Jr.'s parents didn't consent to the plea.

And new arguments that Bartley didn't know lesser convictions could carry lesser punishments.

Poston also argues that Bartley Jr.'s former attorney Mike Hatmaker pressured Bartley Jr. to accept the last-minute deal without consulting with anyone, especially his parents.

Bartley Jr. is currently serving 45 years in prison in connection with the Campbell County School shooting in November of 2005.
