A third student has died from injuries received when a teenager opened fire at the Ohio boy's high school cafeteria on Monday.

Demetrius Hewlin, 16, was reported dead Tuesday 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.

Russell King Jr., another victim of the shooting was reported dead earlier the same morning. They were among five students who have been injured by the gunfire of teenage suspect T.J. Lane, who was reported to have targeted their table in the cafeteria. Daniel Parmertor was the first to die just hours after the shooting Monday.

The cause and manner of death of this case are under ongoing investigation and will be released upon completion, said Hugh Shannon of the Cuyahoga County Medical Examiner's Office in a statement.

Among the injured teens, one 17-year-old remains in hospital in critical condition. Another 18-year-old girl is also in hospital in serious condition, according to USA Today.

T.J. Lane has been identified as the gunman who opened fire in Chardon High School in Ohio on Monday, according to ABC News and CNN.

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.

I just can't believe it. I don't think it's real, Komertz told CNN. And I just, it kills me that I saw someone hiding, and now that someone is now dead.

A teacher -- identified by students as Frank Hall -- helped chase the gunman out of the school. Police say they arrested the suspect a short time later in the township of Chardon.

Before Lane was confirmed as the shooter, 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.
