LINCOLN, Neb. (AP) — A judge has ordered a state psychiatric hospital to release an ailing man who in 1992 tried to shoot up a Lincoln college classroom of students.

Retired Judge Paul Merritt Jr. says 66-year-old Arthur McElroy has become too feeble to present a danger to anyone. Merritt says McElroy is to be released no sooner than June 1 from the Lincoln Regional Center.

Court records say McElroy tried to fire a military carbine into a science class of about 20 students, but the weapon jammed. A judge later ruled that McElroy was insane and not responsible for his actions.

Records say McElroy has since been diagnosed with chronic kidney disease and other maladies.

McElroy is expected to go to a local nursing home.
