A judge in Tyler has ruled that a 17 year old high school student who stabbed a teacher to death in his classroom a year and a half ago is not competent to stand trial, and must be sent to a state  hospital for 90 days where he'll be evaluated by state psychiatrists.

17 year old Byron Truvia is charged with murder in the stabbing death of his special education teacher, Todd Henry, at John Tyler High School in September 2009.

At a competency hearing in Tyler, Dr. Timothy Proctor, a forensic psychologist for the Smith County District Attorney's Office, said Truvia is one of the most dangerous individuals he has ever encountered, and his  mental illness is so pervasive it interferes with his intellectual abilities.

Defense attorney Jim Huggler said after the 90-day evaluation period he expects two psychiatrists at Vernon State Hospital will examine his client and issue two medical certificates, which state law requires to commit Truvia to a mental health facility.

There is no statute of limitations on murder, and the Smith County prosecutor says if Truvia is ever found competent to stand trial he will "absolutely" do so -- even if he is 50 years old.
