CHICAGO - Wyndham Lathem, the former Northwestern University professor found guilty of first-degree murder in the 2017 stabbing death of his boyfriend, Trenton Cornell, was sentenced to 53 years in prison on Tuesday.[1]



Cook County Judge Charles Burns called the killing of Trenton Cornell-Duranleau “cold-blooded” and an “execution” as he sentenced Wyndham Lathem, 47, who was found guilty of first-degree murder in October.

Back in October, jurors in Cook County deliberated less than two hours before returning the guilty verdict against Wyndham Lathem, 47, a renowned microbiologist whom Northwestern fired after he fled the Chicago area following the killing.

Cornell-Duranleau was stabbed more than 70 times on July 27, 2017, by Lathem and Andrew Warren, a British man who Lathem had paid to come to Chicago to commit the murder together, prosecutors said.

During nine days of testimony, prosecutors described Lathem as a coldblooded killer who stabbed defenseless 26-year-old Trenton James Cornell-Duranleau.[2] Defense attorneys argued their client was a bystander framed by the actual killer, alleged co-conspirator Andrew Warren, a British national who pleaded guilty to his role in the slaying.

Lathem testified during his trial that Warren alone stabbed Cornell-Duranleau during what started as a methamphetamine-fueled sexual encounter involving the three men.

Warren in 2019 pleaded guilty to first-degree murder as part of a plea agreement that called for him to testify against Lathem in exchange for receiving a 45-year prison sentence.[3]

Warren, who was an Oxford University financial officer at the time of the slaying, testified that he flew from England to Chicago to meet Lathem and take part in a pact to kill each other before agreeing to kill Cornell-Duranleau at Lathem’s suggestion.

He testified that he did, in fact, stab Cornell-Duranleau, but only after Lathem had already begun stabbing him.
