This is the personal account of Melissa Jesperson Moore, whose father was the Happy Face Killer. I am always interested in the accounts of family members of people who are known serial killers, because the person that we know from trials and media can be a completely different person at home. By her account, Keith Jesperson was a violent person with moods that caused her to walk on egg shells. I cannot imagine growing up in a home with such turmoil, my parent being a serial killer, and having to reconcile that. This was terrifying.
