I call it twinkle eye because his eyes shined so much. His smile lit up the stage every time he stepped foot on it! We were not easy on him the first time he auditioned and told him to work hard and come back again. The same thing happened the next year he auditioned, work hard and comeback," Murphy told Fox News Digital. "That would have been the end for most people, but he persevered and came back again. He still had to fight for his life that 3rd year with his solo. What I saw next was unlike any solo I had seen before. His music was a symphony that was playing, and Twitch started to dance and show us all the instruments being use but through his body. The musicality of it was mesmerizing and a defining moment in Twitch's dance career."

"Those are the moments that I cherish the most, when a dancer seems to be one with the universe, music, and choreography. Needless to say, I was crazy over it and from that moment on Twitch started to soar. I was so proud of him because I had a very small part in his big career," she continued. "Twitch was an inspiration to millions with his work ethic and determination and showed many young children that no matter what your circumstances are you can make it if you work hard! Twitch I love you to the moon and back! I wrap his family Allison, Maddox, Zaria and Weslie with love and prayers. Dear Twitch RIP, the world will miss your shining light!"
