The mother of one of three County Armagh boys who ended their lives within the last month has said she is trying to comprehend her son's actions.
The Samaritans said the young needed to talk about their problems
Wayne Brown from the Laurelvale area was one of three 15-year-olds at the same school to take their own lives.
A minister who has been liaising with the families said there was no evidence of a suicide pact.
Dorothy Brown, who described her son as "happy and outgoing", said she had no idea why her son had ended his life.
"I can't believe that Wayne has done this. I can't believe it at all," she told the BBC.
"We are breaking our hearts, we wouldn't want to see this happen to another family."
All three of the teenagers were in the same year at Craigavon Senior High School.
Lee Walker was a classmate of Wayne's and he died on Friday. One week ago, a third boy, James Topley, died in the same way at the same spot.
Rev Brian Harper said rumours were a problem
Principal David Mehaffey said: "First and foremost, these are tragedies for families and local communities but the school is also a community and everyone here has been deeply affected by the loss of our three students.
"We are also aware that this has had a major impact on the school community, our young people, their families and the staff.
"The school is trying to provide all of the support which it can in conjunction with the officers from the Southern Education and Library Board's Critical Incident Team, who have been tremendously helpful in recent days."
Reverend Brian Harper said while there was no explanation for what had happened, he did not think there had been a suicide pact, but that rumours were causing problems.
"The community has gone into freefall hysteria over the weekend," said the local minister.
"Parents have been told that their children are dead. Children are receiving text messages that their best friends are dead.
"They are going absolutely hysterical, and once text messaging starts, it flies through the whole community.
"There hasn't been a single bit of truth to any of the rumours."
The Samaritans have warned of the dangers of speculating about the cases.
