A woman was arrested Wednesday night in a road rage beating of an elderly driver earlier in the day, police said.Jessica Vasquez (pictured), 19, was taken into custody after she assaulted Evelyn Page, 81, who she thought was driving slowly in the 6200 block of South Meridian Street, on Indianapolis' south side, according to Indianapolis Metro police.Police said Vasquez sped around Page and then slammed on her brakes, forcing the elderly woman to stop.Then, according to police, Vasquez jumped out of her car, opened the driver's-side door of Page's car and began beating her.Police said the victim tried to get away, but that Vasquez pulled her out of the car and continued beating her, forcing her to fall into two lanes of traffic.Page's face was bloodied and her leg was broken in 14 places, 6News' Jack Rinehart reported. She will also have to undergo knee replacement."This is a crime that is outrageous, something that we don't normally see," said IMPD Detective Wendall Daniel. "We don't normally see a female, 19 years old, beating an 81-year-old woman."Witnesses followed Vasquez's car as she sped away and were able to give police a license number, which led to her arrest."It was through the help of a lot of Good Samaritans today that we were able to put this case together so quickly," Daniel said. "We had civilians who saw this and stopped to help the victim."Vasquez expressed remorse in a profanity-laced interview with 6News as she was taken to a police station."I don't have anything to explain to you," Vasquez said. "I hope she's feeling better tomorrow."Witnesses told police that Vasquez had as many as three young children in her car when the incident occurred.Vasquez could be charged with felony battery and confinement, police said.
