A Psychopath serial killer whose head's been kept in a jar since 1841: Diogo Alves

Serial killers are Psychopathic people who are pleased with killing people and who do their job with care and diligence. Diogo Alves was a Spanish born serial killer, where he murdered 70 people from 1836 and 1840. Diogo used to steal and falsify keys, and this was how he managed to gain access to the Reservato de Mae Aguas das Amoreiras. Basically, an underground gallery that lead to the Aquedato das Aguas Livres. His preferred site of murder. His victims were poor passersby. After robbing them, Diogo blindfolded his hapless victims, dragged them to the top of the aqueduct and threw them. A 65 meter drop ensured instant death. Between 1836 and 1839, he repeated this process some 70 times. But soon after, his luck ran out and the law sentenced to death by hanging. But it’s what happened next that makes this one of history’s most interesting stories. Scientists at the time wanted to study Alves’s head, to determine the origin of his murderous nature. For this reason, they had his head removed from his dead body and preserved in a jar for study, where it has remained ever since 1841. Portuguese film, Os Crimes de Diogo Alves, was made in 1911 about his crimes.
