Investigators in the Zantop case have obtained court orders for the release of Robert Tulloch and James Parker's school records and are now looking to interview several of the suspects' teachers.
Dave Potter, superintendent of the Chelsea school said that he believes the police are looking for Tulloch and Parker's grades, attendance and medical records, all of which are kept confidential as required by Vermont state law for all students, The Boston Globe reported.
He also believes that at the court's request, the district is making some records available to the police and that a lawyer for the school district is handling the matter.
The Chelsea school district is also offering the teachers legal counsel if they want it, Potter added, saying that the boys' teachers from as far back as kindergarten may be interviewed.
Tulloch, who was a senior, had completed most of the requirements necessary to graduate. Parker, a junior, had attended Spaulding High School in Barre, Vt. for his sophomore year but transferred back to Chelsea.
According to recently released records, investigators also seized and searched a green Subaru station wagon owned by Parker's parents to conduct forensic testing on a spot of blood on the passenger-side floor mat.
The car matches the description given by Paul Newcity, a resident of Canaan, N.H., to police of a car he saw pulling out of the Zantops' driveway at approximately 2:30 on the day before the murders.
Also, the two SOG Seal 2000 knives that were allegedly used to kill the Zantops were sold to Parker by a dealer in Massachusetts.
James Fox of Scituate, Mass., who owns Fox Firearms, sold two military-style knives to Parker over the Internet and then helped investigators find the two boys, according to an affidavit reported in the Patriot Ledger of Quincy and The Boston Globe.
Police contacted SOG dealers after finding two SOG knife sheaths in the Zantops' home.
Fox told investigators that he had sold 84 SOG Seal 2000 knives on line, but only Parker purchased two in one order.
According to Scituate police, Fox did not break any laws by selling Parker the knives as Massachusetts law does not regulate the sale of most knives.
Fox, however, denied the reports -- after being read the affidavit that referred to the sale of the knives, Fox told The Globe, "That is absolutely false, but I have nothing to say."
Both Tulloch and Parker told police in separate interviews on Feb. 15 that Parker had bought the knives in order to cut branches and build a fort in the woods, but the knives were too big so they sold the knives to someone at an Army and Navy store in Burlington, Vt., either the weekend of the murders or the weekend before.
Police found two SOG knives, both with missing sheaths, in a stack of magazines in Tulloch's bedroom.
The knives -- that had DNA consistent with Susanne Zantop's -- matched the sort believed to have been used in the murders, according to court documents.
Parker's fingerprints also matched those found on one of the sheaths in the Zantops' home, while a bloody footprint found at the scene matched Tulloch's boot.
