March 27, 2001 (CONCORD, N.H.) – The New Hampshire Attorney General has released documents detailing a trail of evidence linking the killing of two Dartmouth College professors with two high school students in a Vermont village more than 30 miles away.
The affidavits say that police found two distinctive knife sheaths in the house where Half and Susanne Zantop were stabbed and traced it to a Massachusetts firm that sold two knives to Robert Tulloch, 17, of Chelsea, Vt. Tulloch and his friend, James Parker, 16, claimed that the knives had been sold, but they were found in later in Tulloch’s home.
The teenagers fled after their first interview with police. They were arrested a few days later at a truck stop in Indiana.
Investigators also say that DNA found on one knife appears to match Susanne Zantop’s.
The Zantops, natives of Germany, both taught at Dartmouth and lived not far from the campus. Investigators have so far released no motive for the killing.
