Nathaniel Heard, 51, of Hampton, N.H., said he got the parts from a friend who harvested a deer found dead on the road, the Portsmouth Herald reported Wednesday.
The Portsmouth High School media teacher was arrested in April on two counts of criminal trespassing, criminal threatening and one count of stalking.
His attorney has petitioned the Portsmouth District Court to lift an order prohibiting him from contact with his ex-wife and children.
Prosecutor Rena Dilando told the court Tuesday the order should stand since both children were disturbed by Heard's actions and are potential witnesses for his trial.
Heard has pleaded not guilty to the charges against him. A trial date has not been scheduled yet.
