We will continue to work to seek justice for Demeria and hold Parson accountable for taking her life. This is a very difficult case for everyone involved, and we ask that you especially keep the family of Demeria in your thoughts and prayers,” said Frederick H. Agee, District Attorney General. The victim's mother said the girls were staying with their grandmother in Humboldt for the summer. She says the issue stemmed over an argument over an iPhone.
