A photograph of Mourad Allafi hangs in the family farmhouse in western Libya three years after he was found in a mass grave. His father wants his killers dead.
Mohamad Allafi believes the prison terms of six years to life handed down by a military court in February to 30 people convicted of murder are not enough.
And relatives of the hundreds of others who were tortured, killed and dumped in row upon row of mass graves in Tarhuna agree with him.
The families who lost relatives in the mass killings say that only the death penalty can ease the pain of those who have lost children murdered "in cold blood".
