A Hong Kong jury watched chilling video Tuesday of a British banker torturing an Indonesian woman and then talking for hours about how he repeatedly raped her and then killed her without feeling guilt or emotion.

The video was shown on the second day of Rurik Jutting's trial for the murders of Sumarti Ningsih, 23, and Seneng Mujiasih, 26, whose bodies were found in his upscale apartment near the city's red-light district in 2014. The case shocked people in the Asian financial hub, which has a reputation for being safe but also significant inequality. It also highlighted the decadent lifestyles of some members of the former British colony's expatriate elite.

Jurors were played about 20 minutes of video in which Jutting apparently tortures Sumarti. The media and public could not view it but heard the audio.

At one point he can be heard saying: "If you scream I will punish you. Understand?" That is followed by the sound of smacking and slapping, and later the sound of a woman whimpering. Jutting then tells her not to cry.

Later, both jurors and the public gallery were shown hours of iPhone video in which Jutting, wearing no clothes, delivers an extended rambling monologue to the camera.
