Man May Plead Insanity in Officer Head Stabbing

A man accused of stabbing a New York City police officer in the head and nearly killing him may pursue an insanity defense.

Terrance Hale's lawyer filed a notice Thursday that his client might argue he's too mentally ill to be held responsible for attacking Officer Eder Loor.

Attorney Edward McQuat said he couldn't yet elaborate on Hale's psychiatric history.

For now, the 26-year-old Hale pleaded not guilty Thursday to attempted murder, assault and other charges. He's being held without bail.

Hale's mother called police April 17 to say he needed medical help. Prosecutors say as the officers followed Hale down a street, he plunged a knife into Loor's head. The blade fractured his skull and hit his brain.

If successful, an insanity defense leads to indefinite hospitalization.
