There was a disturbing incident late Monday when a masked, gun-wielding bandit forced his way into a home on Morningside Drive south of Porterdale. This punk knocked down a 64-year-old grandmother when she answered the door and pointed a handgun at her 20-year-old grandson, who ran off and locked himself into another room to call for help. The intruder may have been armed, but he didn't know he was dealing with a feisty granny, who grabbed on and struggled with him.
