ROCHESTER, N.Y. — A Rochester man accused of attacking his girlfriend with a machete pleaded not guilty in Monroe County Court on Thursday.

Judge Julie Hahn arraigned David Lampman on a grand jury indictment charging him with attempted murder and assault.

The machete attack on April 18 left Tina Schreib severely wounded in her apartment on Dewey Avenue. News10NBC spoke with her sons, who said their mom lost part of her skull, her liver, and other body parts in the attack. They say it’s a miracle that their mother is alive.

Rochester Police arrested Lampman at a gas station in Dansville the day after the attack.
