Shannon L. Remus, 26, is charged in Wisconsin's Dane County with being party to the crime of hiding a corpse. She appeared in Pierce County Superior Court on Wednesday, where she opted not to fight extradition, deputy clerk Melissa Engler told The Associated Press by telephone.
Remus, a U.S. Army police officer with the rank of private, was arrested by Wisconsin deputies Tuesday at the Lewis-McChord military base.
Remus's husband, 28-year-old Jeffrey Vogelsberg, is charged in Wisconsin with torturing and killing Matthew Graville in Mazomanie last summer. Remus is charged with being party to the crime of hiding a corpse.
Kerry Glasoe-Grant, Remus's temporary public defender in Pierce County, did not immediately return a message seeking comment.
A criminal complaint accuses Vogelsberg of regularly abusing Matthew Graville, his 27-year-old half-brother, at the home of Robert L. McCumber in July 2012. McCumber said he heard Vogelsberg administer an especially brutal beating one night, and McCumber awoke to find Graville dead on a couch the next morning.
By that point Vogelsberg and his mother were on their way to Missouri to attend Remus's graduation from a military academy. McCumber told investigators he called Vogelsberg to inform him of his half-brother's death, and Vogelsberg ordered him to wrap the body in plastic and store it in a freezer.
When Vogelsberg and Remus returned to Wisconsin, they and McCumber took the body out of the freezer and the two men buried it in a secluded wooded area, the complaint said. McCumber, who is also charged with being party to the crime of hiding a corpse, said he complied because he was afraid Vogelsberg would kill him otherwise.
After Vogelsberg was arrested he told detectives he brought Remus to the secret burial site and asked her if anything seemed suspicious or out of place.
Remus asked him if this was where Graville was buried and Vogelsberg replied, "The less you know the better," according to the complaint.
Remus denied to investigators that her husband ever took her to the woods.
Officials in Washington's Pierce County recorded a number of phone conversations from jail in which Vogelsberg allegedly told his wife that the most she could be accused of doing was joining him in the woods to look for anything suspicious. Using an expletive he told her to keep her mouth shut and she agreed.
During Vogelsberg's preliminary hearing last month McCumber testified that Vogelsberg and Remus told him to bring a change of clothes when they buried Graville because the clothes they wore during the burial would have to be burned. He said the three gathered together clothes and other items from the burial and used kerosene to burn them in a steel drum the next day.
Lt. Col. Gary Dangerfield, a spokesman for the military base where Remus was stationed, said she entered the Army 12 months ago and had been at the base as a military police officer since July. He said he couldn't release her disciplinary records but added that he wasn't aware of any history of Remus being disciplined.
