An Oxford University employee and a US professor have been charged in Chicago with murdering a 26-year-old hair stylist found with more than 40 stab wounds.
Somerville College's Andrew Warren, 56, and Professor Wyndham Lathem, 42, are accused of killing Trenton Cornell-Duranleau in the academic's Chicago apartment.
Chicago Police announced on Saturday that they had both been charged with first degree murder after they were returned to the city from California, where they handed themselves in following a nationwide manhunt.
Their charges came after a post-mortem examination found the victim, who police say was in a personal relationship with Lathem, had methamphetamines in his system.
Warren, who says online he lives in Swindon, Wiltshire, was suspended from his job as senior treasury assistant after the body of the man, originally from Corunna, Michigan, was found mutilated on July 27.
Microbiologist Lathem, since sacked by Northwestern University, plans to plead not guilty, according to his lawyer Kenneth Wine.
