The North Dakota Supreme Court ruled none of Arthur Kollie's rights were violated, including when prosecutors showed a video of Jupiter Paulsen when she was alive.
Arthur Prince Kollie faces up to life in prison without parole, but that maximum sentence could be lowered to 15 years if the murder conviction is vacated.
The defense is expected to argue Arthur Kollie is not criminally responsible for the death of Jupiter Paulsen. Prosecutors are likely to suggest he lied about having a mental illness to avoid punishment.
Arthur Kollie is accused of stabbing and strangling Jupiter Paulsen, but he claims he was talking to himself as he walked near the place where the attack took place.
