LAWRENCE, Kan. (AP) — A competency evaluation has been ordered for a 17-year-old Lawrence boy accused of killing his grandmother.

Court proceedings against the teen have been suspended pending the results.

The teen was 16 in December when police found his 67-year-old grandmother, Deborah Bretthauer, dead in the apartment they shared. The teen is charged in juvenile court, but prosecutors have filed a motion to try the teen as an adult.

If the boy is convicted of the juvenile first-degree murder charge, he could face up to 60 months in prison, or to the age of 22. In adult court, he could face more than 40 years in prison.
