A British man accused of butchering a Chicago hairstylist<\/a> as part of a twisted sexual fantasy with a Northwestern University professor has accepted a plea deal and will testify against his co-defendant in exchange for a 45-year prison sentence, prosecutors said.<\/p>\n Andrew Warren, a onetime Oxford University financial officer, was set to go on trial next week alongside his co-defendant \u2014 former Northwestern microbiology professor Wyndham Lathem \u2014 in the July 2017 stabbing death of Lathem\u2019s boyfriend, 26-year-old Trenton James Cornell-Duranleau.<\/p>\n But Warren, 58, agreed Monday to plead guilty in the horrific slaying of Lathem\u2019s boyfriend, who was nearly decapitated and found stabbed 70 times at the professor\u2019s apartment in Chicago.<\/p>\n \u201cTis true,\u201d Warren said, when asked if his confession was genuine, the Chicago Tribune reported<\/a>.<\/p>\n Prosecutors in Cook County have said Warren and Lathem, 44, chatted online for months prior to the killing and ultimately plotted to kill Cornell-Duranleau before taking their own lives, according to the outlet.<\/p>\n Warren also agreed to testify against Lathem, who has pleaded not guilty in the slaying. His trial date has not yet been set, the newspaper reports.<\/p>\n Warren signed a written plea agreement, but a judge kept details of the deal sealed until he could meet with Lathem\u2019s attorneys next week when the former Northwestern professor is scheduled to return to court.<\/p>\n A judge also issued a gag order on attorneys in the case, barring them from discussing the high-profile killing that led to a nationwide manhunt before Lathem and Warren were later arrested in California<\/a>. Both remain held without bail in Chicago.<\/p>\n Lathem lost his post at Northwestern after he fled Chicago, while Warren was suspended from his job as a financial officer at Somerville College, which is part of the University of Oxford system.<\/p>\n Prosecutors said Monday that Lathem began the planned attack by stabbing Cornell-Duranleau as he slept, while Warren restrained him and struck him with a lamp while stabbing him, the Chicago Sun-Times reports<\/a>.<\/p>\n The pair had planned to kill themselves after Cornell-Duranleau, but instead fled the apartment and started a two-week road trip that included stops at a public library where they made large donations in victim\u2019s name, prosecutors said.<\/p>\n<\/p><\/div>\n
