(CBS/AP) CHARDON, Ohio - A third student died Tuesday morning in the surburban Cleveland high school shooting that left two other students dead when a teenager allegedly opened fire in the cafeteria on Monday.
Demetrius Hewlin, a student from Chardon High School, and who was previously listed in critical condition, passed away, according to a hospital statement. His family released the following statement:
"We are very saddened by the loss of our son and others in our Chardon community. 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."
News of Hewlin's death came hours after another student, Russell King Jr., was declared brain dead, authorities said Tuesday. The Cuyahoga County Medical Examiner's Office received the word about King Jr. just before 1 a.m. Tuesday, office administrator Hugh Shannon said in a statement. It was unclear whether King remained on life support; the statement referred to him as both deceased and brain dead.
"The cause and manner of death of this case are under on-going investigation and will be released upon completion," Shannon said in a statement. A spokeswoman at MetroHealth System said Tuesday morning that no information on his condition was available.
King, 17, was one of five students injured when a suspect identified by a family lawyer as TJ Lane began shooting at Chardon High School Monday morning. King was studying alternative energy at nearby Auburn Career Center and like the others who were shot was waiting for a bus for his daily 15-minute ride to the center. Student Daniel Parmertor died hours after the shooting.
Law enforcement sources told CBS News that Lane -- who says he was a victim of bullying -- warned his friends about his plans two days in advance. Sources said the suspect is cooperating with authorities. He is scheduled for an appearance in court Tuesday afternoon.
According to statistics from the U.S. Secret Service, which started compiling data on school shootings after the attack at Columbine High School in 1999, at least one other person had some prior knowledge of an attacker's plan in 81 percent of incidents. In 59 percent of incidents, more than one other person had some prior knowledge.
Of those incidents where another person knew about the attack in advance, 93 percent of those people were the attacker's friend, schoolmate or sibling.
A student who saw the attack up close said it appeared that the gunman targeted a group of students sitting together and that the one who was killed was gunned down while trying to duck under the cafeteria table.
Lane's family is mourning "this terrible loss for their community," attorney Robert Farinacci said in a statement.
