( CNN ) -- The high-pitched breathless appeal from a young girl to a 911 dispatcher poignantly captures the panicked uncertainty students felt as a teenager roamed Chardon High School , picking off students . `` We just had a shooting at our school . We need to get out of here ! Oh my God ! '' the girl screams , her voice trembling . The dispatcher asks the girl if she saw the shooter . `` No , '' the girl says beginning to cry . `` No . I did n't . I just saw the gun . '' The girl 's sob-filled plea is among 911 tapes authorities released Tuesday as they continued their investigation into the shooting at the suburban Cleveland school that left three dead , two wounded and a close-knit Ohio community reeling . Sophomore T.J. Lane has confessed to taking a .22-caliber gun and a knife to the school Monday morning and firing 10 rounds , said Geauga County Prosecutor David Joyce . After a preliminary hearing Tuesday , Joyce told reporters the 17-year-old will most likely be tried as an adult . `` Absolutely , '' Joyce said . `` It 's a matter of law in the state of Ohio . At 17 years old , committing an act like this . '' Joyce predicted Lane will be charged with three counts of aggravated murder `` as well as other counts . '' Lane will continue to be held in detention , and charges must be filed by Thursday , the judge at the hearing ordered . Police have said the motive behind the shooting remains unclear , and Joyce added that the teen picked his victims indiscriminately . `` I guarantee that this was an aberration , this does not represent our community , '' he said . `` He chose his victims at random . This is not about bullying . This is not about drugs . This is someone who is not well . '' Lane told authorities he stole the gun from his uncle , a source told CNN on Tuesday . Then , just before class started Monday , witnesses say Lane silently walked up to a table of students in the school cafeteria . The 911 tapes detail the uneasy moments that followed as the school went on lockdown and police feverishly searched for the gunman . In one call , a student who fled the school tells a dispatcher he saw the shooter . `` His name is Thomas Lane , '' the boy says , his calmness belying the situation . `` He 's somewhere in the building . As soon as I saw him pull the gun and start shooting , I ran outside because I did n't want to get in the way of it . '' He tells a dispatcher that he saw a few students get sprayed by bullets . `` They were laying on the ground in blood , '' the boy says . Another call follows , from someone hiding in a teacher 's lounge . Alarmed voices buzz in the background . `` We just need somebody down here as fast as possible , '' the caller begs . `` I want to go home . I want to go home so bad . '' The voices in the room rise as the group realizes the door to the lounge wo n't lock . `` Everybody quiet down . He could be out there , '' the caller says , his voice dropping to a whisper . By the time the carnage ended , the gunman had shot five people , three of them fatally : Daniel Parmertor , 16 , who died Monday ; Demetrius Hewlin , 16 , who died Tuesday morning ; and Russell King Jr. , 17 , who was declared brain dead early Tuesday . Another student wounded in the shooting remained hospitalized Tuesday . A fifth victim was released , officials said . Monday 's death toll might have been higher had it not been for the actions of assistant football coach and study hall teacher Frank Hall . Students said Hall chased the gunman out of the school , and police arrested the suspect nearby a short time later . `` I wish I could have done more , '' Hall told CNN affiliate WEWS . Classes in the tight-knit community of 5,100 , about 30 miles east of Cleveland near Lake Erie , are to resume Friday . But staff , students and parents will be encouraged to return to district schools for visits and counseling on Wednesday and Thursday , Superintendent Joe Bergant said . Geauga County Sheriff Daniel McClelland said the community has a long way to go before it can put the shooting behind it . `` Now we move to another important phase , '' he said . `` And while the investigation continues and we still look for the why and what and who , we now deal with a community looking to heal .
