Report: Alleged school gunman from violent family The teen who authorities believe was behind a deadly shooting Monday in Chardon, Ohio, had violence in his life from early on, Cleveland's Plain Dealer newspaper reported. The father had been warned to stay away from the teen's mother at least once, records reportedly showed. Police have not formally identified the suspected gunman, but students, parents of students and local media said his name was T.J. Lane. It was not clear whether T.J. Lane and his father had any contact, the newspaper reported. The suspect's family said through attorney Bob Farinacci that they were struggling to comprehend what had happened a day after the worst U.S. high school shooting in nearly a year. T.J.'s family has asked for some privacy while they try to understand how such a tragedy could have occurred and while they mourn this terrible loss for their community," the statement read. Officials believe T.J. Lane opened fire inside a high school cafeteria at the start of the classes on Monday, hitting five students. Sixteen-year-old Daniel Parmertor was killed, 17-year-old Russell King Jr. was later declared brain dead, and three others were wounded, police said. "He had no emotion on his face, he was just shooting," a Chardon student told WKYC. Travis Carver, another student present in the cafeteria at the time said the expression on T.J. Lane's face was "straight determination." Second teen confirmed brain dead in Ohio school shooting The suspect was taken into custody near his car a half-mile from the suburban Cleveland school after football coach Frank Hall chased him from the building, according to FBI officials. T.J. Lane was not a student at Chardon High School. He attended the nearby alternative school Lake Academy in Willoughby, which serves at-risk students. Students may have been referred to the school because of academic or behavioral problems. 'Good kid' When asked about the suspect, his family's lawyer called him a "good kid." His grades are pretty impressive," Farinacci said. Student in school shooting: "I went into panic mode" "He would never really talk about his family," Haley Kovacik, who knew T.J. Lane, said. But you can always tell he had a very sad look in his eyes all the time. He usually just kept to himself. Kovacik said she never saw him get bullied, but said it could have happened, as he was "very quiet." "He never really stood up for himself very much," she said. His now-deleted Facebook page showed one picture of him bare-chested and glaring at the camera and another behind a huge teddy bear that bore a heart and the words "Be Mine," according to the newspaper. Ian Sanborn and Travis Carver, who were both in the Chardon High School cafeteria when a teen gunman opened fire, talk to TODAY's Ann Curry about the harrowing experience. He listed "primitive hunting" among his interests, the newspaper reported. "The family wanted me to convey to the citizens of Geauga County and Northeastern Ohio that the family is devastated by this most recent event," Farinacci said in the statement.
