TYLER (November 2, 2009)--A state district judge Monday in Tyler declared a 16-year-old boy competent for trial in the classroom stabbing death of a high school special education teacher.

The boy is accused of stabbing Todd Henry, 50, in the heart in a classroom at John Tyler High School in Tyler on Sept. 23.

Defense attorney Jim Huggler told Judge Floyd Getz in Tyler Monday that he had spent about 30 hours in discussions with his client.

He said most of the youth's answers "are monosyllabic, and he doesn't understand or remember our conversation."

Huggler said the Texas Youth Commission had diagnosed his client as schizophrenic in 2007 or 2008.

But, prosecutor Taylor Heaton said a state hospital found the boy to be "alert and oriented, and his though process seems goal-directed" in May.
