The plea hearing for Calhoun College student David Light ’09, who was arrested in July for possession of illegal assault weapons and bomb-making materials, has been postponed to the end of November, a clerk at the New Haven Superior Court said Thursday.

Light’s hearing, which was scheduled to take place yesterday, has been set for Nov. 27.

“His presence at the hearing was excused,” William F. Dow III ’63, Light’s attorney, said.

On July 16, Light arrived at his room in the former Beta Theta Pi fraternity house to find police — who had a warrant for his arrest — searching his bedroom. Police said they found an AK-47, an AR-15 assault rifle, a .50-caliber sniper rifle, a Russian M-91 infantry rifle, a 12-gauge shotgun, several pistols and 4,000-5,000 rounds of mixed ammunition.

Light was arrested for allegedly shooting blanks from a handgun into the ceiling of the common room at the Beta house and threatening a visitor to the fraternity who was concerned about Light’s behavior.

Light was arraigned on several charges, including two counts of illegal possession of assault rifles, 23 counts of possession of armor-piercing ammunition, 13 counts of reckless endangerment in the first degree and one count of criminal attempt to commit the manufacture of bombs.

Dow said Light is expected to plead not guilty to the charges.

Meanwhile, Yale officials have maintained their position on Light’s status with the University. University spokesman Tom Conroy said Light remains under emergency suspension from the University. Yale College Assistant Dean Jill Cutler, who serves as the secretary of the Executive Committee — the University’s disciplinary council — declined to comment last week on Light’s status with the community.
