A grieving family were sent the head of their dead grandfather in a Hellman's mayonnaise box.
Veronica Sosa was horrified when a delivery of the large cardboard box was made which contained the remains of her grandfather Luis Sosa.
The head, which had become little more than skull, was originally believed to belong to a missing 40-year-old woman in the city of General Roca in central Argentina.
But forensics discovered it was actually the head of Mr Sosa, in his 70s, who went missing from his home in January last year.
While Mr Sosa's heartbroken family were told they could not have his remains returned to them until he investigation ended, they were appalled when his head was delivered to their home.
Packaged in the mayonnaise box with tape sealing its edges, the family said it was as if their grandfather was treated like "nothing".
They shared a picture of the box on social media, writing: "Can their treatment of you be more rubbish?
"One year and eight months we have been waiting for you and looking for you and they deliver you as if you were nothing. Like this! In a box of mayonnaise."
Ms Sosa slammed the authorities for their treatment of her grandfather and the family, adding: "We are only a number to them and those that do not stay quiet are regarded as a nuisance.
"You are going to have to keep working Mr District Attornies because I am not going to stop until I know what happened do Don Sosa, my grandfather.
"When I find out you will not have a place to hide. Luis Sosa did not allow himself to die in a garbage dump.
"Luis Sosa is not just a skull."
The family say they still have not been able to bury Mr Sosa as they are yet to receive a formal death certificate.
