Lathem is charged in the July 2017 killing of Trenton James Cornell-Duranleau, a 26-year-old hair stylist from Michigan who was stabbed dozens of times in Lathem’s Chicago high-rise condominium. Lathem, a renowned microbiologist, and Andrew Warren, an Oxford University financial officer who authorities say flew to Chicago from England to participate in the killing, were arrested in Northern California after an eight-day manhunt. Prosecutors said that the two planned the killing to fulfill an apparent sexual fantasy.
