HENRIETTA, N.Y. (AP) — A woman who bought two guns used by a former neighbor in a deadly Christmas Eve ambush of firefighters has pleaded not guilty to a state charge of filing a falsified business record.

Dawn Nguyen made a brief court appearance on Tuesday in Henrietta Town Court. The 24-year-old is free on the condition she not leave Monroe County except to attend college classes in a neighboring county.

Nguyen is accused of lying on a form when she bought guns later used by ex-convict William Spengler Jr. to kill two firefighters and wound three other first responders in Webster. She faces the same charge in federal court.

Her lawyer says Nguyen's family for a time lived next door to Spengler, and she knew him as "Uncle Billy."
