The victim, Vahid Lazer Monouchehri, had gone missing since widespread protests on January 8,9.
His body was handed over to relatives on Thursday with marks of gunfire and blows from a butcher’s cleaver, the family said.
Manouchehri was buried the following day under tight security in the village of Lazerban near Tonekabon, in Iran’s northern Mazandaran province.
Born on April 14, 1985, Monouchehri was a father of one and originally from Lazerban but had been living alone in Tehran. His family says they were unaware that he had taken part in the protests.
“There was no idea exactly when, where, or under what circumstances Vahid was killed,” the family said.
On Thursday, the Kahrizak forensic medical center contacted the family and asked them to travel to Tehran to collect their son’s body.
When they asked about the cause of death and why they were being contacted only after such a long delay, they say they were told: “There are many bodies here and we don’t know; just come and take the corpse.”
