( CNN ) -- Family and friends of 16-year-old Daniel Parmertor , one of three students killed in an Ohio school shooting , said their final goodbyes Saturday as he was laid to rest . `` I just ca n't believe what happened . He was honestly the sweetest person I 've ever met . He 's such a good person and I ca n't believe he 's gone , '' said Parmertor 's friend , Gabby Cveljo , CNN affiliate WEWS reported . Funeral services for the slain student were held at the Church of St. Mary in Chardon , Ohio , the network said . Mourners marched silently to the church , carrying the American flag . Others had signs with hearts and stood outside , wrapped in blankets against the cold . Parmertor was killed this week when a lone gunman opened fire on students in Chardon High School 's cafeteria . Two other students were hospitalized and another was grazed by gunfire . The shooting rocked the school and the community of 5,100 people about 30 miles east of Cleveland . Authorities say T.J. Lane , 17 , is charged him with three counts of aggravated murder , two of attempted aggravated murder and one of felonious assault . The latter is related to the student who was grazed by a bullet . Prosecutor David Joyce filed charges against Lane on Thursday in juvenile court . The defendant 's next court appearance will be Tuesday , and a hearing scheduled for March 19 will discuss a motion to transfer his case to an adult court . Lane 's friends have said that the teen had a troubled childhood . His parents had both been charged with domestic violence against each other , according to court documents . His father also served prison time for assaulting a police officer and was charged in an assault on another woman . `` I think there 's a lot of kids that go through things like that . That does n't give them the right to kill other people , '' said Bob Parmertor , Daniel Parmertor 's grandfather . `` No one has the right to shoot other people because they 've had a rough life . ''
