A 16-year-old Oregon boy has been arraigned as an adult on aggravated murder and rape charges in the slaying of a 5-year-old girl.

Authorities say Dustin Michael Wallace entered no plea Monday in Douglas County Circuit Court in the death of Sahara Dwight.

The charges filed against the Roseburg boy in a district attorney's information are so-called Measure 11 charges, which call for teenagers 15 and older to be prosecuted as adults.

There was no immediate word on when a grand jury would consider the case.

The boy was arrested Friday at the home he sometimes shares with his father and the victim's mother. Police say he also lives with his mother in Hugo, Okla.

The girl's mother had called 911 saying her daughter was unconscious.
