MORENCI -- The investigation into the disappearance of three young boys from Morenci, Michigan has become a murder investigation. Andrew, Alexander and Tanner Skelton have  been missing since Thanksgiving. Their father, John Sketon, is facing kidnapping charges in their disappearance. Morenci Police Chief Larry Weeks now says this is no longer a missing person's case but a murder investigation instead. He says that when the time is right he's sure charges will be filed.
