University professor, Oxford employee arrested over U.S. murder

Chicago police say the 56-year-old Warren, who lives in England, came to the USA recently for the first time.

Guglielmi said in an email Thursday that the men are at-large but "we have an idea of their whereabouts".

Lathem, an associate microbiology professor at Northwestern, was booked into the Alameda County jail. Andrew Warren, 56, also surrendered to police in neighboring San Francisco. They will appear separately in court before being extradited to IL, where they face charges of first-degree murder in the killing of 26-year-old Trenton James Cornell-Duranleau. It was not immediately clear when that would happen.

"Both individuals will be held accountable for their actions and we hope today's arrest brings some comfort for the victim's family", the Chicago Police Department said in a statement.

Before the men were taken into custody Friday, Chicago police said Lathem sent out a video to family and friends, apologizing for his role in the stabbing. The video raised concern among investigators that Lathem might kill himself.

"We are also thankful both men are safely in custody and this did not end in further tragedy", the statement said.

Warren arrived in the United States three days before Cornell-Duranleau's death and was seen in surveillance video leaving the building with Lathem the day of the stabbing.

Chicago police said the two will go before an Oakland court and be returned to Chicago.

Authorities haven't disclosed a possible motive for the killing.

Conroy was not involved in Warren's surrender and did not know how it came about.

It was around 8:30 in the evening on July 27, when Chicago police said they found they found Cornell-Duranleau's body with "several lacerations" after responding to a call requesting a well-being check.

Lake Geneva police say a person handed the sum in cash to a library employee, but detectives admit they do not know why. The victim was found last week stabbed to death in a River North high-rise apartment building. When police opened the door they found Cornell-Duranleau's body.

The pair had been named as suspects in the attack that was so brutal the blade of the knife used in the murder had broken off, police said.
