AUGUSTA, Maine — Maine's medical examiner says a 15-year-old girl police believe was lured to her death by a man using a phony Facebook profile died from asphyxiation.

The official cause of Nichole Cable's death was given Thursday as "asphyxia due to compression of the neck." Authorities haven't elaborated.

Chief medical examiner Dr. Margaret Greenwald released the autopsy results after consulting with the state police crime lab, which has been reviewing evidence.

Twenty-year-old Orono resident Kyle Dube (DOO'-bee) is being held on murder and kidnapping charges in Nichole's death.

Police say he used a fake Facebook profile to lure her from her Glenburn home before killing her May 12. Her remains were found in woods in nearby Old Town days later.

Dube's lawyer is out of town and unavailable for comment.
