Spanish police have arrested a man in Barcelona in connection to the Jan. 7 death of a Dartmouth College student Crispin Scott. Scott, who was to graduate from Dartmouth in 2013, was found dead in Barcelona, Spain, days after arriving in the city to participate in a study abroad program offered through Portland State University. Early autopsy reports indicated drug overdose was the cause of death, according to the Spanish newspaper El Periodico de Catalunya on Saturday. However, the final autopsy report revealed the amount and type of drugs, a powerful barbiturate, indicated his death was not the result of a night of partying as first suspected of the college student, though friends and family said he was a good student and athlete. The final autopsy results caused police to investigate the background of the landlord of the apartment Scott had been found in. The landlord had acted cold during the investigation, police had noted, according to El Periodico. Police learned the man, whose name has not been released, had been accused by a young man in 2009 of drugging and violating him. Police arrested and charged the landlord with murder on Wednesday, according to El Periodico. He is accused of giving Scott a drink containing a dissolved barbiturate. After police searched the man's home and another Barcelona apartment he frequented they found two dozen photos of young people, unconscious and in different states of dress and undress. Police believe he had photographed them after giving them a mixture of tranquilizers. Police believe these young people had been sexually assaulted by the man and that possibly this landlord is a serial rapist. Scott had just arrived in Barcelona to participate in a two-month Academy of Liberal and Beaux-Arts program sponsored by Portland State University when he was found dead.
