The eldest son of former Mozambique President Joaquim Chissano has died, while being investigated over the 2000 killing of journalist Carlos Cardoso.
Joaquim Chissano is returning home early after the death
Nympine Chissano, 37, was found dead at his home in the capital, Maputo, state radio reported.
The cause of death has not been determined but the radio said he had been ill for some time.
Cardoso died while investigating corruption allegations. Mr Chissano denied any involvement.
The man convicted of the assassination, Anibal dos Santos, known as Anibalzinho, has said Mr Chissano ordered the killing - accusations the authorities were investigating.
Dos Santos is serving a 30-year jail sentence. He twice escaped from custody but was recaptured both times.
Cardoso had been investigating the disappearance of $14m from Mozambique's main state bank when he was murdered.
Joaquim Chissano is on holiday in Europe but made plans to return home early when his son died.
Last month, he won a $5m prize awarded to former leaders in Africa who have helped promote good governance.
