Mystery over motive for children's murderpublished at 14:15 Greenwich Mean Time 17 November 2017
Only Endris Mohammed himself knows why he killed his children and attempted to murder his wife, police say.
"As part of our investigation we spoke to people who were in his taxi on that day and they say he was happy, chatting and he seemed very normal," Det Insp Justin Spanner said.
Neither had his wife noticed a change in his behaviour, Mr Spanner added.
An investigation showed he had no history of mental illness and contrary to his claims of money worries his bank account was not overdrawn, police said.
