Friends and colleagues described David as smart, funny and an all-around great guy. They had no idea that he had suffered from debilitating bouts of depression for years. While Kim was aware of her husband's depression, she did not realize the seriousness of his condition.
David says he requested a week off of work to try and deal with his illness. On one of those days, January 20, 2006, Samantha and Tessara were home sick from school. Kim left the girls with David while she ran out to get a haircut. What David never told Kim or anyone else—not even his therapist—was that he was having secret thoughts of killing his family.
