Search for Northwestern professor tied to fatal stabbing narrowing 'by the hour'

A Chicago Police spokesman on Thursday said authorities are narrowing their search "by the hour" for a Northwestern University professor and an Oxford University employee believed to have been involved in a fatal stabbing in the River North neighborhood.

"We know where they might be, and we have more information coming in," Anthony Guglielmi said about Wyndham Lathem and Andrew Warren.

"We want to facilitate a safe surrender."

Meanwhile, Guglielmi provided more details from the night 26-year-old Trenton H. James Cornell-Duranleau was killed in Lathem's luxe apartment building on July 27.

At 8:30 p.m., an attendant working the front desk received a cryptic phone call in which a male caller said, "There may have been a crime committed in Room 1004. You need to check it out."

The attendant called the room, and when he got no response, called police. Officers entered the apartment with the building manager, and discovered a "gruesome scene," Guglielmi said.

On Monday a Cook County judge issued arrest warrants for Lathem, 42, and Warren, 56, a payroll assistant at Oxford University's Somerville College in England.

Guglielmi said detectives believe the pair have fled Illinois, but their passports have been flagged by the State Department, and the U.S. Marshal Service has joined the search.
