Man who killed Dartmouth professors at 17 to get a chance at parole in about 20 years, judge rules
Judge Sets Parole Timeline for Dartmouth Murder Convict
Man who killed Dartmouth professors at 17 – Robert Tulloch, currently 43 years old, will become eligible for parole consideration in approximately two decades following a judicial decision announced Monday. The Vermont native was merely 17 when he and his companion murdered two married professors from Dartmouth College a quarter-century prior. Under the new arrangement, Tulloch may seek release when he reaches 62, matching the age of victim Half Zantop at the time of his death.
Legal Background and Supreme Court Influence
Following his guilty plea to first-degree murder charges in 2001, Tulloch received an automatic life sentence without possibility of parole for the brutal stabbing deaths. However, a landmark 2012 United States Supreme Court decision declared that mandatory life-without-parole sentences violate constitutional protections for juvenile offenders. This precedent was subsequently applied retroactively, opening doors for hundreds of young offenders serving life terms across the nation. Five men in New Hampshire alone, convicted of teenage murders, benefited from this legal shift. Tulloch’s resentencing proceedings represented the final hearing among those five cases. Originally scheduled for three days in Grafton County Superior Court in North Haverhill, the matter was resolved through an agreement between prosecution and defense teams, eliminating the need for extended proceedings.
Victim Impact and Courtroom Proceedings
During Monday’s hearing, a restrained Tulloch kept his gaze downward while court officials recounted the gruesome details of the stabbings. He offered a personal apology to Veronika Zantop, one of the professors’ daughters, who participated via video connection. The victim’s daughter, a psychiatrist and mother of two boys, expressed understanding regarding adolescent brain development but maintained that Tulloch’s case differed significantly.
“This wasn’t a crime of passion or retribution,” she stated. “He wasn’t using substances, he wasn’t psychotic. There was just sheer depravity.”
She emphasized that Tulloch carefully orchestrated the murders and executed them with calculated precision rather than emotional impulse.
Sentence Determination and Future Implications
Tulloch’s legal representatives had advocated for a minimum term between 30 and 40 years, citing comparative analysis of juvenile homicide cases throughout New Hampshire and nationally. Judge Lawrence MacLeod ultimately imposed a 45-year minimum before parole eligibility, with Tulloch potentially being considered for release in 2046.
“The agreed upon sentence provides certainty that Tulloch will remain incarcerated for a substantial period of time, allows Tulloch to pursue some measure of rehabilitation, and it secures important protections for the community,” New Hampshire Attorney General John Formella explained.
Defense attorneys Richard Guerriero and Oliver Bloom highlighted Tulloch’s institutional record, noting substantial maturation since his initial misconduct. According to prison documentation, he committed no significant violations after 2012 and experienced no minor infractions since 2017. Therapy records indicate he has demonstrated considerable remorse for what he characterizes as an unforgivable act stemming from distorted adolescent reasoning.
The Original Crime and Aftermath
James Parker, Tulloch’s accomplice, testified that the teenagers grew restless with their existence in Chelsea, Vermont. They devised a scheme targeting random strangers, intending to rob them and relocate to Australia. Over several months, the pair approached residents in New Hampshire and Vermont under the pretense of conducting environmental surveys. Susanne Zantop, 55, directed Dartmouth’s German studies department, while her husband Half Zantop instructed students in Earth sciences. Parker, then 16, described how Tulloch stabbed Half Zantop before ordering him to assault Susanne Zantop. Both women received multiple stab wounds. Physical evidence, including fingerprints on a knife sheath and a blood-stained boot impression, connected the teenagers to the scene. After police questioning, they escaped Vermont and traveled westward by hitchhiking. Authorities apprehended them weeks later at a truck stop in Indiana. Parker, who cooperated fully with investigators and accepted a guilty plea for accomplice liability to second-degree murder, secured parole in 2024 at age 40.
