Trenton Cornell-Duranleau, a 26-year-old licensed cosmetologist, was stabbed to death in a Chicago-area apartment, and now authorities are seeking a university professor and employee in his murder.
Officials believe the duo have left the state and are "armed and extremely dangerous"-and, as Michael Sneed at the Sun-Times first reported, that they made a donation to a Wisconsin library in the victim's name right after the murder".
They repeatedly stabbed Trenton Cornell-Duranleau in Lathem's apartment before fleeing, according to Chicago Police. However, incoming and current Northwestern students needn't worry about having class with Lathem this quarter (Northwestern operates on a quarter-based rather than semester-based schedule), though, as a university spokesperson confirmed that he's been placed on administrative leave and is banned from campus.
He lived with his sister and his boyfriend, and was struggling with the death of his father several months ago, the Chicago Tribune reported.
Police believe Duranleau was trying to break off a relationship with Lathem.
Chicago Police department chief communications officer Anthony Guglielmi urged both men to turn themselves in and said the force's search "will only intensify". His connection with Lathem is now unknown, but his and Lathem's passports have been flagged.
He attended Creston High School in Grand Rapids, Michigan and studied and received his cosmetology license from Stanley Harris School of Cosmetology in Holland, Michigan.
Public records show that Lathem, 42, lists the apartment unit where Cornell-Duranleau was found as his residence.
In a statement, a spokesman for Oxford and Somerville College said the university had been in contact with police in the United Kingdom "and are ready to help the USA investigating authorities in any way they need".
In a statement which was released to the media, she added: "Our Family is deeply saddened by the death of our son".
His mother, Mischelle Duranleau, posted a message on Facebook over the weekend asking for prayers "as we navigate this very dark part of our Journey". Lathem's faculty page has been removed from the university website.
Oxford University said it had been in contact with police in the United Kingdom about Mr Warren and was "ready to help the U.S. investigating authorities in any way they need".
