Diogo Alves
Diogo Alves (born
Diego Álvarez; 1810 – 19 February 1841) was a Spanish (Galician)
serial killer and robber who was active in Portugal in the late 1830s. Between 1836 and 1840, he killed 70 people. The crimes he committed were all in the area of the
Águas Livres Aqueduct, thus earning the title "Aqueduct Murderer". He was
sentenced to death and hanged on 19 February 1841, along with one of his accomplices. His head was separated from his body and placed in a flask to preserve it for scientific purposes, and it is now a tourist attraction.
