“Why would you do that? That’s your mother, that’s your grandmother,” Virginia George said.

“To be in your own neighborhood and for someone to attack you like that, that’s very vicious,” another person added. “So that goes to show you there’s something wrong with him. There’s some kind of mental disorder. He needs help.”

“That’s bad, very bad. If I should catch somebody like that, I’d hold the person until the police come,” said Jonathon Oberko.

Police said the victim reported the attack Monday, after she went to a hospital for evaluation.

Surveillance video shows the suspect leaving the building. He’s described as 5-foot-8, 170 pounds, and last seen wearing a black hooded sweatshirt, black du-rag and carrying a black costume mask.
