17 Years Old Boy Pleads Guilty To Shooting His 16 Years Old Girlfriend To Death.



A 17-year-old boy from South Dakota has admitted to fatally shooting his 16-year-old out-of-state girlfriend during an argument last fall.

Michael Gavin Campbell pleaded guilty to first-degree manslaughter for killing Shayna Ritthaler, from Upton, Wyoming.

'We got into an argument and then I shot her,' the defendant said during his change-of-plea hearing at Meade County Court. 'I shot her in the head.'

Campbell faces 55 years in prison when he is sentenced later this year.


Ritthaler's body was found on October 7 in the basement of the home Campbell shared with his mother after the pair met on an online dating site.

Asked by Judge Kevin Krull if he had any justification for killing Ritthaler, the teen replied, 'No.'

In court, the defendant referred to the victim as his girlfriend.

Both the prosecutor and the defense agreed to ask the judge to sentence the boy to 55 years in prison.

Krull said he plans to follow that recommendation and that if he changes his mind, the defendant could withdraw his guilty plea.

The teen originally pleaded not guilty and not guilty by reason of insanity to alternate counts of first- and second-degree murder.
