Warren then left the room and returned with two kitchen knives, allegedly joining in on the stabbing.
Authorities have said the attack on Cornell-Duranleau, a MI native who moved to Chicago previous year, was so brutal that the blade of the knife investigators believe was used in the stabbing was broken.
Cornell-Duranleau went to sleep in Lathem's apartment, at which point Lathem texted Warren that it was time to kill Cornell-Duranleau, prosecutors said.
Prosecutors allege that the men ultimately planned to kill one another - with Warren shooting Lathem as he stabbed him - after committing several murders.
In the messages, which he sent to his parents and friends, the now-fired Northwestern professor, who did academic work on the bubonic plague, says that "he is not the person people thought he was", according to the prosecutor.
Witnesses later told officers they had heard a fight and screaming at around 5am and detectives found two knives at the scene, one of which had been broken.
Warren came to the apartment, and Lathem entered the bedroom where Cornell-Duranleau was sleeping while Warren stood in the doorway. Warren, 56, also turned himself in to authorities.
Stab wounds were found on his back, chest, shoulder and abdomen, with further cuts on his arms, chin, neck, hands and wrists.
The prosecutor told the court that the victim's last words were to Lathem: "Wyndham, what are you doing?"
The body was discovered at around 8.30pm on July 27 after the building's front desk received an anonymous call that a crime had taken place on the tenth floor.
Lathem and Warren were scheduled to appear in bond court at 1 p.m. Authorities say Cornell-Duranleau suffered more than 40 stab wounds to his upper body during the July attack in Lathem's high-rise Chicago condo.
When the victim's body was moved, he appeared to have been almost decapitated, prosecutors said, and he had sustained multiple wounds that would have been mortal in and of themselves.
A post-mortem examination showed Mr Cornell-Duranleau had the drug methamphetamine in his system.
Lathem, 43, had been held in a California jail since turning himself in August 4 in California.
Prosecutors said Lathem paid for Warren to visit the USA and the two of them then chose to kill victims of Lathem's choosing.
The two arrived in Chicago late Friday night to face murder charges in the death of the 26-year-old. Detectives were questioning the men Saturday.
