The family of Frank Meza, the 70-year-old marathoner who was found dead Thursday amid cheating allegations, spoke exclusively to Inside Edition about his death. Asked whether the allegations against him killed her husband, Meza's wife, Tina Nevarez, replied, "Yes, I do believe that." He was found dead Thursday. The cause of death was suicide, officials said. The family said they didn't anticipate he would take his own life but believe cyberbullying led him to do it.
