The jury trying the case of alleged serial killer Stephen Port, who is accused of killing four young men with fatal doses of date rape drug GHB, is set to resume deliberations for a second week.
The 41-year-old chef allegedly met men on gay dating websites and lured them to his flat in Barking, east London, where he spiked their drinks.
Jurors have been told he rendered them unconscious so that he could carry out his rape fantasies, having searched for extreme pornography online.
Over 15 months, the bodies of his alleged victims were found dumped in or near a graveyard some 500 metres from his home.
Port denies 29 charges against a total of 12 men including murder, manslaughter, administering a substance with intent, rape and sexual assault.
