António Luís Costa

António Luís Costa (born 1953) is a Portuguese retired GNR soldier and serial killer from Santa Comba Dão.

[6] The third and last victim was Joana Oliveira, who went missing on 8 May 2006; her body was recovered from under a bridge based on directions given by Costa.

[6][14] In addition, the defence claimed the rights of the defendant were not respected because he was treated as a guilty psychopathic serial killer.

[6] On 31 July 2007, the court found Costa guilty of all charges except for the crime of hiding Isidoro's body, since she was still alive when she was thrown into the Atlantic Ocean.

[17] The case raised some criticisms towards the Portuguese rule that sets 25 years in prison as the maximum penalty.
