A woman who was found stabbed to death at her home in London and her husband and children who subsequently died in East Sussex have been officially named by police.
Laura Cecilia Navarrete De Figueira, 47, her husband Adelino Gabriel Figueira de Faria, 57, and their children Claudio Gabriel, 10 and Joaquin Alejandro, seven, were found dead on 5 March.
Police found the bodies of a man and two boys just before 5pm on the beach at Birling Gap seafront in East Sussex.
Ms Navarrete De Figueira's body was found at around 6pm when police arrived at her home in South Road, Twickenham, southwest London, after concerns were raised about the family's welfare.
She was found dead at the scene with stab wounds.
The bodies at Birling Gap were later confirmed to be the woman's husband and two young sons, after Sussex Police contacted Scotland Yard when they learned officers were looking for a man and his two sons.
A post-mortem examination found that Ms Navarrete De Figueira died from multiple stab wounds.
An examination of Mr Figueira de Faria showed that he died from multiple injuries consistent with falling from height.
The same cause of death was given for the two boys.
