Specific details of his passing are unknown at this time. He had made sporadic appearances for independent promotions since departing from ROH in 2009.
Whybrow suffered from bipolar disorder and had a breakdown in 2009, which he described as "the absolute worst event" of his life. He also had past drug issues that led to his release from ROH.
Independent wrestler Chris Hero, a friend of his, commented on his passing on Twitter.
"We lost a dedicated friend and an overwhelmingly talented performer this morning," he wrote. "Alex Whybrow aka 'Sweet & Sour' Larry Sweeney has passed.
"We spent a few yrs together on the road & Alex was gifted beyond measure. He could enthrall you with colorful stories from his personal life or he could captivate thousands with his undeniable charisma. I loved him & my heart is with his family, friends & his countless fans. First he was my student & he transcended that almost immediately. I will forever cherish our in depth conversations & time spent together. Love you man. Miss you. Rest in Peace."
