Andrew Warren, who works at Oxford's Somerville College, and Wyndham Lathem, teacher of microbiology at Northwestern University, were arrested separately on Friday (4 August) in California, some 3,200km away from the crime scene where 26-year-old Trenton Cornell-Duranleau was killed.
On July 27 around 8:30 p.m. local time, officers responded to a call at an apartment registered to Wyndham Lathem, an associate professor at Northwestern, Chicago police said.
"Our primary focus is to facilitate a safe surrender and we strongly encourage Professor Lathem and Mr. Warren to do the right thing and turn themselves into any police department in the USA or contact CPD [the Chicago Police Department] and we will make any necessary accommodations", Guglielmi said. Andrew Warren-a 56-year-old senior treasury assistant at Somerville College of Oxford-surrendered at a police station in San Francisco, according to the Tribune.
Chicago Police spokesman Anthony Guglielmi announced the development on Twitter, writing: "CPD has gotten word that Prof".
Earlier on Friday, police said that Lathem allegedly had sent a video message to family and friends in which he apologized for his part in the killing.
"We are also thankful both men are safely in custody and this did not end in further tragedy", the statement said.

Libya's eastern-based parliament, which is also recognized internationally, is a rival to Tripoli and is allied with Hifter. Italy's lower house voted by 328 to 113 in favour of the mission, while the upper house voted by 191 to 47.
Guglielmi said in an email Thursday that the men are at-large but "we have an idea of their whereabouts". Lake Geneva police said the man making the donation did not give his name.
Guglielmi said the victim was in a relationship with Lathem and knew Warren.
'I've never seen where suspects in a homicide would make a donation in the victim's name, ' said Lake Geneva police Lieutenant Edward Gritzner.
Officers arrived to find Cornell-Duranleau dead.
In a weird twist, police said that on the day of the slaying, but before the body had been discovered, Lathem and Warren drove about 80 miles (128 kilometers) northwest to Lake Geneva, Wisconsin, where one of them made a $1,000 cash donation to the public library there in Cornell-Duranleau's name.
