The first of two men charged in a grisly River North murder has arrived back in Chicago after being extradited from California, two weeks after they surrendered to authorities in the Bay Area after a nationwide manhunt.

Andrew Warren, a payroll assistant at Oxford University, arrived in Chicago shortly before midnight, according to a pool report from CBS Chicago.

According to authorities in California, Wyndham Lathem, a former microbiology professor at Northwestern University, as well as Warren, were longer held in jail in California as of Friday afternoon and were being transported to Chicago.

Warren’s arrival in Chicago had not been confirmed as of 12:30 a.m. Saturday.

Lathem’s attorney, Adam Sheppard, told the Chicago Sun-Times that the former professor was expected back in Chicago Friday night. Warren will be represented by a public defender.

“It’s possible there could be a bond hearing tomorrow,” Sheppard said. “Sunday or Monday would be more likely.”

Lathem and Warren are accused of fatally stabbing Trenton Cornell-Duranleau in Lathem’s River North apartment last month. Autopsy results released this week said Cornell-Duranleau was stabbed 47 times, with significant incised wounds to his neck.
