Jamey Rodemeyer's sister Alyssa on Wednesday's edition of CNN's Anderson Cooper 360 talked about the bullying of her brother after his death.

Jamey committed suicide after being bullied for coming out gay. The 14-year-old freshman at Wiliamsville North High School outside Buffalo, New York was found dead outside his home on September 18.

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,” he said in the clip.

During her appearance on CNN, Alyssa told host Anderson Cooper that she found her brother's body hanging outside their home.

Finding him was “rough, but … I didn't have time to soak it all in 'cause I was in a state of shock and I was trying to do everything, you know, call 911, get my parents, try to save him. It didn't register at the time, I guess.”

Alyssa also discussed an incident that occurred during a homecoming dance after Jamey's death.

When a Lady Gaga song began playing, “We all started chanting for him,” Alyssa said. “We were all jumping around and we were singing to it. … A little group of like three of his prior bullies, as we were chanting, they started yelling stuff back at us. They were saying that they were glad he was dead, and just basically that, and some obscenities and things.” (The video is embedded in the right panel of this page.)
