A Massachusetts judge is scheduled to formally sentence a teenager who has been convicted of first-degree murder for fatally stabbing another student at a suburban Boston high school.
Middlesex Superior Court Judge Jane Haggerty is expected to sentence John Odgren on Friday to a mandatory life sentence with no possibility for parole.
A jury convicted Odgren on Thursday, rejecting a defense assertion that the then 16-year-old was legally insane when he stabbed 15-year-old James Alenson in a boys' bathroom at Lincoln-Sudbury Regional High School on Jan. 19, 2007.
Odgren's lawyers said he had a long history of emotional problems and disorders, including Asperger's syndrome, attention deficit hyperactivity disorder and depression.
But prosecutors depicted Odgren as a calculating killer who brought a carving knife to school, then picked a victim at random.
Defense lawyers plan to appeal.
