A man faces felony theft charges for draining his grandmother’s bank account of more than $10,000 behind her back.The grandson, Matthew Shawn Young, 32, is charged with five counts of forgery and one count of theft over $10,000. He will face hearing before General Sessions Judge Bill Locke on March 15.His charges come after his grandmother missed her bank statements for the months of November and December of 2015.“She went to the bank to get a copy of her statements and found that around $10,500 had been taken from her account without her knowledge,” said sheriff’s investigator Kevin Murphy. Murphy said his investigation led him to look at the surveillance video taken at one of the bank’s ATMs.“It showed Matthew Shawn Young withdrawing from the ATM,” Murphy said, noting he found the suspect had taken her ATM card and PIN number from her purse in October.“He would replace the card and then go get the card again when he needed money,” Murphy said.
