Jamey Rodemeyer's parents, Tim and Tracy Rodemeyer, say their son continues to be bullied even after his death.

Jamey is the 14-year-old junior high school student who committed suicide after being bullied for coming out gay. The teen, who had just started his freshman year at Williamsville North High School outside Buffalo, New York, was found dead outside his home on September 18. More than 500 people showed up to pay their respects to Jamey at his funeral held on Saturday.

In a YouTube video posted in May, Jamey said Lady Gaga had inspired him. “Lady Gaga, she makes me so happy, and she lets me know that I was born this way. And that's my advice to you from her. People are born this way. All you have to do is hold your head up and you'll go far,” he said in the clip. “Just love yourself and you're set … It gets better.”

The Rodemeyers told TODAY host Ann Curry on Tuesday that their daughter Alyssa faced open hostility during a homecoming dance.

“She was having a great time, and all of a sudden a Lady Gaga song came on, and they all started chanting for Jamey, all of his friends,” Tracy said. “Then the bullies that put him into this situation started chanting, 'You're better off dead!' and 'We're glad you're dead!' and things like that.”

“I can't grasp it in my mind,” Tim said. “I don't know why anyone would do that. They have no heart, that's basically what it comes down to.”

The Rodemeyers urged parents to talk to their children.

“My message to the parents is, 'Badger your kids and make them talk,' or get them the help they need,” Tim said.

“We tried to get Jamey to talk constantly but he just kept it in, he just put up a brave face. Just don't let it go,” Tracy added. (The video is embedded in the right panel of this page.)

Singers Ricky Martin and Lady Gaga have drawn attention to Jamey's death.

Martin tweeted to his nearly 4 million followers, “This needs to stop now,” while Lady Gaga paid tribute to the teen during a Saturday performance in Las Vegas.

“Bullying is for losers,” she told the audience.
