Purdue double homicide suspect in custody

WEST LAFAYETTE, Ind. – Purdue University officials announced that the suspect being sought in connection with the murder of two women on the West Lafayette campus last week is in police custody in Amherst, N.Y.

Zhan Yin

Zhan Yin, 27, of the People's Republic of China, was arrested between 7:30 and 8 p.m. Tuesday (8/7) shortly after Canadadian officials denied him entry into that country via the Rainbow Bridge near Niagara Falls. The graduate student in biological sciences was still driving the red Ford Taurus rental car he used to flee the Oklahoma State University campus in Stillwater, Okla., on Monday morning.

"Border officials on the American side of the bridge ran a routine check on his identity after he had been turned back on the Canadian side," said Joseph L. Bennett, Purdue's vice president for university relations. "He was arrested by Amherst police shortly afterward."

A team of Purdue police investigators is traveling to Amherst Wednesday (8/8) to question Yin and continue the investigation there. Bennett said Indiana officials will begin extradition proceedings to bring Yin back to the state.

Yin is charged with two counts of murder in connection with the deaths of Purdue doctoral student Yeunkyung Woo, 31, and her sister, Hyo Kyung Woo, 29, who was visiting the West Lafayette campus from Chicago. Their bodies were discovered Friday morning (8/3) in the Purdue Village student apartment where Yeunkyung Woo lived. Both women were South Korean nationals.

Tippecanoe County Coroner Martin Avolt said tonight that both victims died sometime Thursday (8/2) evening from blunt force trauma and incised wounds.

Yin and his wife, Jun Ke, live at 118-12 Marshall Drive, West Lafayette. Jun Ke is a Purdue doctoral student in mathematics. Their apartment building also is located in Purdue Village.

According to a news release issued by Oklahoma State University on Monday (8/6), Jun Ke told authorities there that she had tried to convince her husband to stay in Indiana and cooperate with investigators, but he wanted to visit a friend at OSU over the weekend first. She contacted Oklahoma State University police after Yin took off in their rented car.
