The Dartmouth College murders refer to the January 27, 2001, stabbing deaths of professors Half and Susanne Zantop inside their home in Etna, New Hampshire, by two Vermont teenagers, Robert Tulloch, 17, and James Parker, 16. Both pleaded guilty. Parker was paroled in June 2024, and Tulloch, whose mandatory life-without-parole sentence was ruled unconstitutional in 2025, is scheduled for a resentencing hearing in July 2026.
Who the Zantops Were
Half Zantop, 62, was a Dartmouth earth sciences professor who specialized in economic geology. Susanne Zantop, 55, held the Parents’ Distinguished Research Professorship in the Humanities, chaired the German Studies Department, and directed the Comparative Literature graduate program. She wrote several books, including Colonial Fantasies: Conquest, Family, and Nation in Precolonial Germany, 1770–1870.1Dartmouth College. In Memory of Susanne and Half Zantop Both were born in Germany and spoke four languages. Colleagues described them as “immensely popular” at Dartmouth.2CBS News.

The Killers and Their Plan
Robert Tulloch and James Parker grew up together in Chelsea, Vermont, a rural town where they attended the same public school and had been close friends for nearly a decade. Tulloch was an honors student who had earned enough credits to graduate early. Parker was a junior, known as the class clown. Prior police contact amounted to paintball incidents and speeding.3New Haven Register. Teens’ Slaying Arrest Stuns Vermont Town
The murders were not impulsive. According to the indictment, the pair began planning a robbery-murder scheme in June 2000. The plan was to force their way into a home, extract ATM cards and PINs from the residents, kill them, and use the money to flee to Australia.4Vermont Public.

They also prepared for the violence itself. Parker studied stabbing techniques in a British military hand-to-hand combat manual at a local library. The two had purchased stun guns online and tested them on each other before Tulloch’s mother found the devices and made them return them.7Rutland Herald.

What Happened on January 27, 2001

How Investigators Caught Them
The case broke on two knife sheaths left at the scene. Investigators identified them as belonging to SOG SEAL 2000 military-style knives and worked backward through dealers who sold that model. On February 14, 2001, James Fox of Fox Firearms in Scituate, Massachusetts, told police he had sold 84 of the knives online. James Parker was the only customer who had ordered two in a single transaction.10Cape Cod Times. Knives in Dartmouth Professor Killings
Interviewed the next day, Parker said he had sold the knives to a stranger at a military surplus store the week before the murders. Both teenagers voluntarily gave fingerprints, which matched prints from the crime scene. A search of Tulloch’s bedroom turned up two knives without sheaths, and court documents said DNA consistent with Susanne Zantop’s was found on the blades.10Cape Cod Times.

After giving prints on February 15, the pair fled New Hampshire in a family member’s silver Audi. They abandoned it at a truck stop in Sturbridge, Massachusetts, and started hitchhiking west toward California.12The Harvard Crimson.

Bill Ward, monitoring CB radio traffic, heard a truck driver asking for help with two young hitchhikers. Ward had seen the suspects on CNN. Posing as another driver on the radio, he offered to take the teenagers the rest of the way. When they were dropped off at the fuel desk, officers arrested both without incident. “They appeared to be very surprised,” Ward said. “They didn’t expect us to move in around them so quickly.”13CNN.

Charges, Pleas, and Original Sentences
Both teenagers were charged as adults with two counts of first-degree murder, but their cases diverged.
Parker, 16 at the time of the killings, took a plea deal. He pleaded guilty to being an accomplice to second-degree murder and agreed to testify against Tulloch. In exchange, he received 25 years to life rather than mandatory life without parole.14Vermont Public.

Tulloch’s defense had signaled an insanity defense, but shortly before trial he pleaded guilty to two counts of first-degree murder. In 2002 he was sentenced to two consecutive terms of life in prison without the possibility of parole.15WMUR. Robert Tulloch Resentencing Order Response
Parker’s Release on Parole
James Parker was granted parole on April 18, 2024, and released from prison on June 7, 2024, having served slightly less than the minimum of his 25-year sentence. At his parole hearing, Parker told the board his actions were “unimaginably horrible” and that “there is not an amount of time or things that I can do to change it, or alleviate any pain that I’ve caused.”14Vermont Public.

The Zantops’ two daughters chose not to publicly oppose Parker’s release. “We felt strongly that it wasn’t our job to comment on whether or not he should be released,” Veronika Zantop said, adding that her views had evolved: “I realized that the world is complex and teenagers are complex.” She said she felt sadness “that a 16-year-old was somehow driven to do this and that his family had to contend with the fallout.”17Valley News.

Tulloch’s Resentencing Fight
Tulloch’s life-without-parole sentence has been in play for more than a decade because of shifting constitutional law on juvenile sentencing. In 2012, the U.S. Supreme Court held in Miller v. Alabama that mandatory life-without-parole sentences for juvenile offenders violate the Eighth Amendment. Courts must consider a juvenile defendant’s age and circumstances before imposing the harshest sentence.18InDepthNH. Judge Rules Life Without Parole for Juveniles Cruel and Unusual in Dartmouth Murders Case In 2014, the New Hampshire Supreme Court held that Miller applied retroactively, entitling Tulloch and three other inmates sentenced to mandatory juvenile life without parole to new hearings.19Juvenile Law Center. Soto v. Gerry, Tulloch v. Gerry, Dingman v. Gerry, Lopez v. Gerry
Tulloch had been seeking resentencing since 2013. On July 31, 2025, Grafton County Superior Court Judge Lawrence MacLeod issued a ruling declaring that mandatory life without parole for juvenile offenders violates the New Hampshire Constitution. MacLeod found such sentences “cruel” because they effectively condemn a juvenile to “death in prison” and “unusual” because they are rare in New Hampshire and increasingly uncommon nationally. He wrote that the state constitution’s protections for individual rights and minors are broader than the federal Constitution’s. If the state constitution permits juvenile life without parole at all, MacLeod ruled, the state must prove “permanent incorrigibility” beyond a reasonable doubt.18InDepthNH.

The New Hampshire Attorney General’s Office asked MacLeod to reconsider. On October 20, 2025, he denied that request, reaffirming that denying any possibility of parole to a juvenile offender is cruel and unusual under evolving standards of decency. He noted that juvenile life-without-parole sentences “could not have been understood or accepted as a penalty for crimes to the framers in 1784,” since life sentences and modern prison systems did not exist then.21Valley News. Dartmouth Professors’ Murderer Legal Victory MacLeod also ruled that prosecutors cannot argue for reimposing the original life-without-parole sentence at resentencing.22Union Leader. Resentencing for Teen Killer Robert Tulloch Moved to July
The resentencing hearing was initially set for April 2026 and continued to July 13–15, 2026, in Grafton County Superior Court. The court will consider Tulloch’s age at the time of the offense, his conduct and rehabilitation over more than 25 years in prison, and whether he falls into the narrow category of juvenile offenders for whom the most severe sentence may still be constitutional.22Union Leader. Resentencing for Teen Killer Robert Tulloch Moved to July Tulloch is 43.
