He was a teenager who didn't quite fit in. His classmates said Billy Lucas was bullied for being different.

The 15-year-old never told anyone he was gay but students at Greensburg High School thought he was and so they picked on him.

"People would call him 'fag' and stuff like that, just make fun of him because he's different basically," said student Dillen Swango.

Students told Fox59 News it was common knowledge that children bullied Billy and from what they said, it was getting worse. Last Thursday, Billy's mother found him dead inside their barn. He had hung himself.

Students said on that same day, some students told Billy to kill himself.

"They said stuff like 'you're like a piece of crap' and 'you don't deserve to live.' Different things like that. Talked about how he was gay or whatever," said Swango.

Principal Phil Chapple doesn't deny that students are bullied in the high school, but he said he didn't know Billy was one of the victims.

"We were not aware of that situation," said Chapple.

It's clear though, on a memorial page created in Billy's honor that many people knew students bullied him. We found comments like "everyone made fun of him"

It's a wake up call to a serious problem the school can't ignore.

"We're discussing where we are going. Where we are looking to establish a committee," said Principal Chapple.

It's a common problem inside Greensburg High School that goes way back.

"I was bullied several times because I was gay. I was called f**, queer. i was thrown up against lockers. I would tell the school officials about it and they would dismiss it," said a former student who did not want to be identified.

He is 21 years old now and the awful memories of high school came rushing back when he heard about Billy's suicide.

"I can't help but take it personally because when all of this was happening to me I was the same age he was. I also attempted to commit suicide."

Other students are speaking out on a facebook page created in Billy's honor and it's obvious that bullies have hurt students at Greensburg High School. Billy's death is a wake up call.
