‘Professor Kim’, Hong Kong’s yoga ball murderer, was my landlord

Khaw Kim Sun was found guilty on Wednesday of murdering his wife and daughter using a gas-filled yoga ball, in a case that has gripped the city. A former Lantau resident tells how she came to rent his decrepit 1,400 sq ft house in the tiny village of Tong Fuk, and how Khaw kept up the pretence of a popular and sociable family man struggling to deal with personal tragedy.
