WICHITA, Kan. (AP) — One of two people charged in the killing of a Wichita State University student has entered a guilty plea.

The Wichita Eagle reports that 23-year-old Isaiah Copridge pleaded guilty Thursday to second-degree murder in the death of Rayan Ibrahim Baba. Copridge also pleaded guilty to aggravated robbery after waiving his preliminary hearing.

The victim was a 23-year-old Saudi undergraduate student. He was found shot in a parking lot of one of the university’s dormitories on Aug. 8. An affidavit says he had contacted Copridge’s co-defendant, Eboni Fingal, about sexual services she advertised online shortly before he was killed.

Copridge faces more than 54 years in prison. His sentencing is set for Feb. 18, just two days after Fingal’s trial is set to begin. She has pleaded not guilty.
