A US-wide manhunt has been launched for an Oxford University employee accused of stabbing to death a hair stylist in Chicago. 
 
 Police put out an all points bulletin for Andrew Warren, 56, a senior treasury assistant at Oxford's Somerville College, warning that he and an alleged accomplice were "armed and dangerous," and officers were told to use "extreme caution" if they were sighted. 
 
 The pair were last seen driving a rented grey 2017 Hyundai car. 
 
 Warren's fellow suspect was named as Wyndham Lathem, 42, an expert researcher of the bubonic plague, and an associate professor of microbiology and immunology a Northwestern University in Chicago. 
 
 They were accused of killing Trenton Cornell-Duranleau, 26 and, according to a court-issued warrant, they allegedly "stabbed him multiple times thereby causing the death". 

 A Northwestern University associate professor and a University of Oxford employee are wanted in connection with the stabbing death of a man in a Near North Side apartment, according to public records. 
 
 
 
 A Cook County judge issued arrest warrants Monday charging Wyndham Lathem, 42, and Andrew Warren, 56, with first-degree murder in the death of 26-year-old Trenton Cornell-Duranleau last week, records show. 
 
 An alert broadcast over police radio says the two should be considered armed and dangerous. Late Wednesday afternoon, Chicago police spokesman Anthony Guglielmi reported no arrests. 
 
 "Our search will only intensify,'' tweeted Guglielmi. "Prof Latham (Lathem) & Mr Warren, do the right thing & turn yourself in to any police dept.'' 
 
 Lathem is an associate professor at Northwestern's Department of Microbiology-Immunology at the Feinberg School of Medicine. In his LinkedIn profile, Lathem said his research is focused on pathogens and the diseases they cause. 
 
 Lathem has been placed on administrative leave and is banned from all Northwestern campuses, according to school spokesman Alan K. Cubbage. He was a faculty researcher at the school's Chicago campus. 
 
 The university is cooperating with the police investigation, Cubbage said.

 Warren is a senior treasury assistant at Somerville College, part of the Oxford University network, according to a university web page. 
 
 
 
 Chicago police officers responded to a 10th-floor apartment in the 500 block of North State Street about 8:30 p.m. Thursday after a maintenance worker reported getting an anonymous call that a crime was committed there. 
 
 
 
 Officers found Cornell-Duranleau dead on the scene. Lathem lists his home at the same address on State Street, public records show. The building is on the same block as the Grand Avenue Red Line station. 
 
 
 
 Cornell-Duranleau died of multiple sharp force injuries, according to the Cook County medical examiner’s office. He had lived in the 2200 block of South Wood Street in the Heart of Chicago neighborhood on the Near Southwest Side, the office said. 
 
 He grew up in Michigan, according to public records. Cornell-Duranleau earned a state license as a cosmetologist in 2011, according to the Michigan Department of Licensing and Regulatory Affairs. 
 
 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." 
 
 According to an obituary posted by the mother, Cornell-Duranleau was born in Lennon, Mich., a small town about 50 miles northeast of Lansing. 
 
 "Throughout his life he loved music and animals," the obituary said. "His enthusiasm for life was infectious. Trenton was a caregiver and loved to help others. His youthful free-spirit fueled his love of cars, video games and cartoons." 
 
 Northwestern was made aware of the investigation into Cornell-Duranleau's death on Monday afternoon, Cubbage said. 
 
 Lathem has been with Northwestern since 2007, according to Cubbage, who said he worked primarily in a research lab. "At some point in the past few years he taught medical students or graduate students, never undergrad,’’ Cubbage said. 
 
 Lathem was not currently teaching and was not scheduled to be in a classroom in the fall, Cubbage said. 
 
 Oxford University, where the other suspect worked, released a statement Tuesday saying it was "not aware of this case, which is clearly extremely concerning. We will liaise with the relevant investigating authorities and provide any assistance that is required.”

 CHICAGO (AP) — Police are searching for a Northwestern University professor and a University of Oxford employee suspected in the stabbing death of a Chicago man and have alerted law enforcement agencies around the country that the pair should be considered armed and dangerous. 
 
 Anthony Guglielmi, a Chicago police spokesman, said Wednesday that a Cook County judge issued first-degree murder warrants for Wyndham Lathem, 42, and Andrew Warren, 56, in the killing of Trenton Cornell-Duranleau. Cornell-Duranleau, 26, was stabbed to death last week in a 10th floor apartment believed to be Latham's in the River North neighborhood. 
 
 Police have not released a possible motive or said how they linked the suspects to the killing, but Guglielmi said security camera footage shows them leaving the building that night. 
 
 Guglielmi said Lathem and Cornell-Duranleau knew each other, but he didn't know any details about the relationship. He said investigators determined that Warren, who lives in England, came to the U.S. recently for the first time, but he didn't know if Warren knew the victim. 
 
 Officers went to the apartment last Thursday night after the person working at the building's front desk called to report that he'd received an anonymous call about a crime having been committed in that unit. Cornell-Duranleau, who lived in the Heart of Chicago neighborhood on the city's lower West Side, was pronounced dead at the scene. The medical examiner's office said he died of multiple sharp force injuries. 
 
 A Northwestern University spokesman, Alan Cubbage, said in a news release that the school is cooperating with the investigation and that Lathem has been placed on administrative leave and banned from entering school property. He said there is no indication that Lathem, an associate professor of microbiology-immunology who has been on the faculty since 2007, is a danger to anyone at the school. 
 
 Warren is a senior treasury assistant at Somerville College in England, which is part of the Oxford University network, according to a university website. 
 
 According to an obituary posted by Cornell-Duranleau's family on the website of The Argus-Press of Owosso, Michigan, Cornell-Duranleau had a cosmetology license. The obituary doesn't say when Cornell-Duranleau came to Chicago, and the family didn't reply to calls seeking comment.
– Police in Chicago have asked law enforcement agencies across the country to be on the lookout for a strange pair of murder suspects: an American bubonic plague expert and a British university treasurer. Wyndham Lathem, a 42-year-old professor of microbiology and immunology at Northwestern University, and Andrew Warren, a 56-year-old treasury assistant employed by Oxford University, are accused of stabbing Trenton Cornell-Duranleau, 26, to death in Lathem's Chicago apartment on July 27, the Telegraph reports. Police say the two men should be considered armed and dangerous. Authorities believe they have fled Chicago, possibly in a rented gray 2017 Hyundai. Chicago police spokesman Anthony Guglielmi said Wednesday that a judge had issued first-degree murder warrants for the pair, the AP reports. He did not discuss a possible motive, but said security camera footage captured Lathem and Warren leaving the River North apartment building the night of the killing. Guglielmi said Lathem and Cornell-Duranleau apparently knew each other. It's not clear how they were connected to Warren, who recently came to the US for the first time. Northwestern University says Lathem, who has been employed by the institution since 2007, has been placed on administrative leave and banned from all its campuses, the Chicago Tribune reports.
