OGDEN -- Eric Millerberg has been charged with child abuse homicide and three other felonies in the death of North Ogden teen Alexis Rasmussen.
The other charges are obstructing justice, unlawful sexual activitiy with a minor and abuse or desecration of a body.
Millerberg's wife, Dea, is charged with desecration of a human body.
The charges were announced in a news conference by Weber County Attorney Dee Smith.
Rasmussen was baby sitting at the North Ogden home of Eric and Dea Millerberg on Sept. 10, the night she was last seen.
The body of Rasmussen, a 16-year-old Weber High School student, was found Oct. 18 in a remote area of Morgan County near the small town of Taggart.
The Millerbergs have been considered persons of interest in the case.
Eric Millerberg has since been sent to prison on unrelated parole violations stemming from drug use.
Dea Millerberg faces drug charges, also unrelated to the Rasmussen case, in 2nd District Court.
A call to a public defender who previously represented Eric Millerberg was not returned Tuesday.
The Associated Press contributed to this story.
Dea Millerberg's defense lawyer, Michael Bouwhuis, said his client is "relieved" to have finally been charged in the case.
"She has always maintained that she did not cause the death of Alexis Rasmussen, and this charge bears that out," Bouwhuis said. "She is very sorry about the untimely death of Alexis Rasmussen and sincerely hopes that the Rasmussen family will someday soon find healing and comfort."
