Monpelier, Vt. ? A man accused of killing two people and wounding two others in a shooting rampage that began at his ex-girlfriend’s home and continued at an elementary school pleaded not guilty Friday, while a prosecutor said the suspect confessed to the crimes.

Christopher A. Williams, 27, was ordered held without bail. He shot himself twice in the head after the rampage Thursday and appeared in court confined to a wheelchair, arms strapped to his sides and feet shackled.

Williams was charged with two counts each of first-degree murder and attempted murder. He was released from a hospital Friday and transferred to jail.

Mental health counselor Joan Tracy told Cashman that Williams had said he wanted to drown himself in a toilet after being arrested Thursday. He was ordered to undergo a psychiatric evaluation.
