OAKLAND, Calif. (KGO) -- A hearing will take place to see if a man is mentally competent enough to stand trial for the stabbing death of a young woman on BART.
John Cowell faces charges for the murder of 18-year-old Nia Wilson at BART's MacArthur Station in Oakland last July.

A judge ruled in December that Cowell was not competent to stand trial at that time.
Since then, Cowell has undergone psychiatric treatment.
