MacDonald case, and illegally wired money from his law firm's bank account. In 1993, Blackburn pleaded guilty to fraud, embezzlement, forgery and obstruction of justice. He was disbarred and served three-and-a-half months in jail. Colette MacDonald's mother and stepfather, Mildred and Alfred Kassab, both died in 1994; she on January 19 and he on October 24. Alfred Kassab had initially believed MacDonald's testimony and been a staunch and vocal supporter of his son-in-law, but he drastically changed his opinion and became one of MacDonald's fiercest adversaries. Initially, Mildred had welcomed a 1971 diagnosis of breast cancer, writing in her diary the cancer would help her in her "desire to just die" following the murders of her daughter and grandchildren. However, her husband's steadfast determination to see MacDonald brought to justice compelled her to assist him in his quest for justice, and she consented to submit to radiation therapy. In 1984, Kassab reflected on the impact the events made on his marriage to Colette's mother, stating: "Most people who go through traumatic things like this, nowhere near as lengthy, almost always end up in divorce, but, with us, it's drawn us closer." With his own health in decline, in 1989 Kassab recorded a message on a tape recorder, stating he wished the recording to be played at any future parole hearings. In this recorded message, Kassab stated: "I want to be sure he serves out his sentence the way it should be served out. I don't want him walking the streets."
