David Carmichael, who killed his epileptic son in July 2004 has for the first time spoken of his pain. In an interview to London Free Press, Carmichael who is at the Brockville Psychiatric Hospital said he was haunted by his son's memories.

''I wouldn't want any family to go through what our family has,'' he said. ''I'm sorry. I miss my son very much.'' Carmichael was a physical activity and sports consultant when he began suffering from depression. He began taking an anti-depressant without consulting anyone and had delusions that his family would be better off if he killed Ian.

''Within a day or two, I was beginning to plan suicides and began thinking my son was going through so much pain himself. Then I started planning a murder-suicide, and then just murder. It became my mission to kill Ian,'' Carmichael told Free Press reporter Jennifer O'Brien. Before he began taking the drug, Carmichael was a loving father.
