Can a convicted felon be an executor of his mother's estate in the state of WV?

My brother has been arrested 38 times, in which my mother always bailed him out. He has been out of jail on bail since Feb., 2012 for 11 felony counts for pill shopping while going to the VA for pain meds. My mother still holds the bond, but has been deceased since November 13, 2012. He lives an unethical life, his utilities such as water, electric and Sudden Link is connected to my Mother’s estate. Mom named him and my oldest brother as executor of her estate. He is not returning any of our calls, or complying with the Realtor/signing disclosure papers to sale her house. He has signed/forged my oldest brother’s name on their joint estate account for purchase of pain medications and to further his own needs. I would like to have him removed from the executor’s position. Can a convicted felon be an executor in the state of West Virginia? Do we as beneficiaries have any recourse to keep him from leaching all her assets? Please help!
