An Ohio teenager who has been identified as the gunman that opened fire at Chardon High School on Monday has arrived at juvenile court for an initial appearance Tuesday, CBS News reported.

T.J. Lane arrived at the courthouse in Geauga County in the afternoon; shortly after a third death in the shooting was confirmed. Demetrius Hewlin, 16, was reported dead  at MetroHealth Medical Center near Cleveland; police later confirmed the death.

We are very saddened by the loss of our son and others in our Chardon community, his family said in a statement released by the hospital. Demetrius was a happy young man who loved life and his family and friends. We will miss him very much but we are proud that he will be able to help others through organ donation. We ask that you respect our privacy during this difficult time.

Hewlin was the third victim to die in the shooting. Daniel Parmertor was the first to die just hours after the shooting Monday. Earlier on Tuesday Russell King Jr, another victim, was also reported dead.

Two victims still remain in the hospital. One 17-year-old boy is in critical condition, while an 18-year-old girl is in serious condition, according to USA Today.

One student who witnessed the attack said the shooter seemed to be targeting one table in the cafeteria. I looked up and this kid was pointing a gun about 10 feet away from me to a group of four kids sitting at a table, Danny Komertz, a 15-year-old student, told the Middletown Journal.

We're not just any old place, Chardon, Chardon School Superintendent Joseph Bergant II said, according to CBS News This is every place. As you've seen in the past, this can happen anywhere, proof of what we had yesterday.

Before Lane was confirmed as the shooter, student Evan Erasmus identified the gunman as Lane, saying that he had been friends with the people he had shot before they drifted apart.

He just came from a really broken-down home and he was living with his grandparents, Erasmus told CNN, saying he was quiet but could be really nice if someone reached out to him.

One of Lane's friends, Haley Kovacik, was shocked when he was identified as the shooter. She described him as a very normal teenage boy.

He did have a sad look in his eyes a lot of the time, but he talked normally, he never said anything strange, Kovacik told CNN. It was a really big shock.

Lane's Facebook Page

In December, Lane posted a poetic rant on his Facebook page that opened a window into his life. In a quaint lonely town, (where there) sits a man with a frown (who) longed for only one thing, the world to bow at his feet, he wrote

Feel death, not just mocking you. Not just stalking you but inside of you, he writes. Wriggle and writhe. Feel smaller beneath my might. Seizure in the Pestilence that is my scythe. Die, all of you.
