CNN has not seen the video and police are not releasing it, but Chicago Police spokesman Anthony Guglielmi characterized it as Professor Wyndham Lathem "apologizing for his involvement in the murder of Trenton Cornell-(Duranleau)." His death occurred the same day that one of the suspects walked into the public library of Lake Geneva, a Wisconsin resort city about an hour's drive from Chicago, and made a $1,000 cash donation in Cornell-Duranleau's name. Both men, who are wanted on charges of first-degree murder, remained at large Friday, though police say they have an idea where they might have fled.

 Chicago police spokesman Anthony Guglielmi said detectives will interrogate Lathem and Warran once they are returned and police will publicly detail the cases against them after those interrogations. Cubbage said Lathem never taught undergraduate students, was not teaching at the time and he was not scheduled to teach in the fall. Prior to the arrests, Lathem had sent a video to his friends and family in which he talks about the biggest mistake of his life, a high-level source at the Chicago Police Department told CNN on Friday. They found Cornell-Duranleau lying face down, dead from stab wounds to his back, law enforcement sources said. In the kitchen, police found a knife with a broken blade in the trash can and another knife near the sink.

 Police had said they believed the two suspects have fled the state. Warrants for first-degree murder had been issued for both men Monday for their alleged involvement in the death of Trenton H. James Cornell-Duranleau, who was found stabbed to death in a luxury Chicago apartment on July 27. Gritzner said Friday there is no indication the suspects are still in that area, but police have been searching just in case. Ninety-five percent of visitors are people from Chicago,” Gritzner said. He could not elaborate on the relationship and could not say how Warren knew Lathem and Cornell-Duranleau. Bosel has been a hairstylist at Timber's Salon in Trenton, Michigan, for 19 years and said Cornell-Duranleau worked there for around a year and a half.
– A manhunt for two university employees wanted in the murder of a Chicago hairstylist ended Friday in California. Wyndham Lathem, 42, a bubonic plague expert who has been an associate professor at Northwestern University since 2007, turned himself in "peacefully" to police in Oakland on Friday evening, NBC News reports. Andrew Warren, 56, a treasury assistant at Oxford University in Britain, surrendered to cops in San Francisco in connection with the death of Trenton Cornell-Duranleau, 26, who was found dead in Lathem's apartment on July 27. The victim died of multiple stab wounds, police said. The men are awaiting extradition to Illinois on first-degree murder charges, CNN reports. On Friday, Chicago police said Lathem sent family and friends a video message apologizing for "his involvement" in the brutal slaying, calling it "the biggest mistake" of his life, per the Chicago Tribune. Police have not released a motive or many details about the murder, but a high-ranking police source tells CNN the "victim was savagely ... mutilated" in Lathem's upscale apartment. Police recovered a broken blade believed to be the murder weapon. They said it was unclear if Warren knew the victim; the Brit was just three days into his first trip to the US when the murder occurred. An odd twist: On the day of the killing, one of the suspects walked into the public library in Lake Geneva, a Wisconsin resort town about 90 minutes northwest of Chicago, and made a $1,000 cash donation in Cornell-Duranleau's name, the Tribune reports.
