Boy facing adult charges after body found in western South Dakota

RAPID CITY, S.D. (AP) - The Latest on the arrest of a teen in death of girl found in his basement in South Dakota (all times local):

A 17-year-old has been charged with second degree murder in the death of Shayna Ritthaler, a Wyoming 16-year-old who went missing Oct. 3.

Shayna Ritthaler was found dead in a Sturgis-area home Monday, Oct. 7.

KOTA-TV reports Michael Gavin Campbell made his first appearance in Fourth Circuit Court in Sturgis Wednesday morning, where the judge set his bond at $1 million.

Campbell's attorneys asked for a $250,000 bond but Circuit Judge Kevin Krull set his bond at $1 million; saying the court finds the facts of the case particularly troubling.

In arguing bond, Meade County State's Attorney Michelle Bordewyk said that Campbell admitted to law enforcement that he and Ritthaler had an argument; the argument turned violent and he shot her.

The court sealed the probable cause affidavit in the case, cutting out access to details in the case.

Campbell is set for arraignment next week.

He's being charged as an adult but since he's a juvenile he can't be sentenced to life in prison if he's convicted but can only be sentenced to a set number of years.

Ritthaler was last seen last Thursday getting into a vehicle at the Coffee Cup in Moorcroft, Wyo. She was found dead Monday in a home in the Blucksberg community near Sturgis.

A South Dakota prosecutor alleges that a 17-year-old boy charged with killing a girl whose body was found in his basement shot the girl after an argument.

The teen is charged as an adult with second-degree murder, which carries a mandatory life sentence upon conviction. The Rapid City Journal reports that he made his initial court appearance Wednesday and will remain in juvenile detention with bond set at $1 million.

The teen is charged with killing the girl, who authorities believe is 16-year-old Shayna Ritthaler, of Moorcroft, Wyoming. She has been missing since last Thursday. Deputies found the girl's body on Monday.

Acting Meade County state's attorney Michele Bordewyk said in court that the defendant was with the victim when an argument turned violent and "he shot her."

The defendant's attorney, Steven Titus, told The Associated Press that he will ask for the case to be returned to juvenile court and that the teen will plead not guilty at his next court appearance on Oct. 17.

A prosecutor in South Dakota says she plans to file adult charges against a 17-year-old boy who was arrested after a girl's body was found in his basement.

Meade County sheriff's officials believe the victim is 16-year-old Shayna Ritthaler, from Moorcroft, Wyoming, who has been missing since Oct. 3.

Acting Meade County state's attorney Michele Bordewyk did not say what charges the teen will face, but that he was expected to make an initial court appearance Wednesday.

Bordewyk tells the Rapid City Journal the boy lived with his mother at the Sturgis area home where the body was found Monday. The victim was found after deputies, working with Moorcroft police, and state investigators searched the home. Authorities haven't disclosed how the girl died.

A 17-year-old boy has been arrested after a girl, believed to be missing from Wyoming, was found dead in his basement in South Dakota.

The Meade County Sheriff's Office says the victim is apparently 16-year-old Shayna Ritthaler, from Moorcroft, Wyoming, who has been missing since Oct. 3.

The body was found Monday at the boy's home near Sturgis after deputies and agents from the South Dakota Division of Criminal Investigation searched the house at the request of the Lawrence County Sheriff's Office, which is working with Moorcroft police.

Meade County Sheriff Ron Merwin has not disclosed the cause of death and isn't sure if the suspect and victim knew each other. An autopsy is scheduled later this week.
