We have been following the case of Samuel See, an assistant professor at Yale University who was arrested on charges of fighting police officers, then taken to a jail where he died the next day.

Further investigation has now led to a conclusion about the cause of death:

Samuel See, the Yale assistant professor found lifeless in jail on Nov. 24, died from a heart attack induced by methamphetamines, the State Medical Examiner’s Office told the News Monday afternoon.

See’s cause of death is listed as “acute methamphetamine and amphetamine intoxication with recent myocardial infarction,” according to the toxicology report released by Chief State Medical Examiner James Gill. See’s death was ruled an “accidental death,” an employee at the medical examiner’s office said. Neither the amount of the substance See consumed nor the time of consumption was clear.

See, 34, was detained on Nov. 23 following a domestic dispute with his husband, Sunder Ganglani. The two men, who were married in May 2013, had mutual protective orders registered against each other following a disturbance in September for which they were both charged with assault in the third degree and breach of peace. When police arrived at See’s home in the afternoon of Nov. 23, called in by See’s sister, and found Ganglani there, officers arrested both men for violating the mutual protective orders.

See struggled with and threatened police on the scene, according to eports from the New Haven Police Department. After receiving treatment at Yale-New Haven Hospital for a cut above his left eye sustained during the arrest, See was detained in a local lock-up center administered by State Judicial Marshals at 1 Union Ave. He was found unresponsive in his cell shortly after6 a.m. the next morning, Nov. 24.

Colleagues and students interviewed in the wake of the death said they had no information about See’s drug use. English professor Katie Trumpener told the News that See was battling both physical and mental health issues, having at one point told her that he was HIV positive. See was on unpaid leave from the English department last Fall following multiple medical leaves. Lindsey Uniat ’15 said See, who was her advisor, told her in Spring 2013 that he was having health issues but that they were “not life-threatening.”

John Rogers ’84 GRD ’89, the director of undergraduate studies for the English department, told the News in a November email that he was “certain” See’s leave was not related to drugs.

Mark D’Antonio, the media director for Yale-New Haven Hospital, declined to comment Monday on See’s particular case, but did say patients brought in under police custody are only released once they are deemed physically fit — the same standards applied to any other patient treated at the hospital.
