A couple are facing life sentences after being found guilty of murdering a teenage boy they accused of witchcraft.
Kristy Bamu, 15, was tortured and drowned in a bath on Christmas Day 2010 by his sister Magalie and her partner Eric Bikubi.
At the Old Bailey football coach Bikubi, 28, and Magalie, 29, of Newham, east London, denied murder but were found guilty.
They were remanded in custody to be sentenced on Monday.
Kristy was in such pain after three days of being attacked with knives, sticks, metal bars, and a hammer and chisel that he “begged to die” before slipping under the water.
He had refused to admit to sorcery and witchcraft and his punishments in a “deliverance” ceremony became more horrendous.
He had come to London with his two brothers and two sisters from Paris to visit Magalie during the Christmas holiday in 2010.
But Bikubi turned on them, accusing them of bringing kindoki – or voodoo – into his home.
He forced them to pray for deliverance for three days and nights and the sisters, 20 and 11, were beaten along with Kristy, until they “confessed” to being witches.
Magalie encouraged Bikubi and beat Kristy until he also confessed to witchcraft.
Sister Kelly, now 21, said: “Kristy asked for forgiveness. He asked again and again. Magalie did absolutely nothing. She didn’t give a damn. She said we deserved it.”
Calling Magalie “an idiot”, Kelly said: “I am sure she still believes even to this day that we are witches. I have no pity for her. She had no pity for us.”
Kristy had 130 separate injuries and died from a combination of being beaten and drowning.
Paramedics called to the flat found Kristy’s brothers and sisters standing in the blood-spattered living room, hysterical, terrified and soaking wet.
Bikubi admitted manslaughter on the grounds of diminished responsibility caused by brain damage, but this was rejected.
He also pleaded guilty to two counts of causing actual bodily harm to the girls. Magalie denied the assaults but was found guilty.
