Marie Osmond's 18-year-old son was remembered at a funeral service Monday with fond words, laughter and music from his famous singing family. Michael Bryan was memorialized by six of his seven siblings as a lighthearted person with a brilliant sense of humor who had a kind and generous heart. “He was a man of his word. He wasn't a talker, he was a doer. He was reliable,” Bryan's sister Rachel Blosil, 20, said, struggling to express herself through tears. “He knew my hopes, he knew my dreams, my secrets, things that nobody knows. He was my best friend.” Police in Los Angeles have said Bryan died Feb. 26 from an apparent suicide after jumping from the eighth floor of the Metropolitan apartment building. An official cause of death is pending the results of an autopsy and toxicology tests. Police said Bryan left a note but have provided no details about its contents. One of five children adopted by Osmond, Bryan previously used his adoptive father's last name, Blosil. Bryan was a first-year student of apparel manufacturing at the Fashion Institute of Design and Merchandising. In 2007, Osmond said her son had entered a rehabilitation facility but did not disclose what he was being treated for.
