EL DORADO ? A missing Kansas college student believed to be the victim of foul play apparently led a double life as an Internet porn star by the name of Zoey Zane.

Nude photos of 18-year-old Emily Sander appeared on a Zoey Zane Web site before she vanished, and investigators are looking into whether her modeling had anything to do with her disappearance last Friday.

“She enjoyed it. She is a young teenage girl and she wanted to be in the movies and enjoyed movies. She needed the extra money,” Nikki Watson, a close friend of Sander’s at Butler Community College, told The Associated Press on Wednesday. “Nobody in El Dorado knew besides her close friends.”

El Dorado Police Chief Tom Boren said FBI and state experts on Internet crime have been called in.

“Investigators are aware that Miss Sander was apparently involved in a Web site situation,” he said. “Allegations that this may factor into her disappearance are being thoroughly investigated.”

Sander was last seen leaving a bar in El Dorado, about 30 miles from Wichita, with a man identified as Israel Mireles, 24, authorities said. Sander and Mireles had met that night at the bar, according to Watson.

After Mireles did not show up Saturday at his job at an Italian restaurant, his employer went to the motel room where he was staying.

“His motel room was found to appear in great disarray, and a large quantity of blood was found in the room,” Boren said. “Bed clothing was found to be missing. The police were called.”

A nationwide manhunt was under way for Mireles and his 16-year-old girlfriend. A rental car he had been driving turned up Tuesday in Texas, where he had family. Those relatives have been interviewed, El Dorado Detective Justin Phillips said, but he declined to say whether they had seen Mireles or knew where he was.

On Tuesday, authorities released a photo of a white bedspread with a floral design and asked for the public’s help in locating it. Divers searched a reservoir near El Dorado on Wednesday.

“Our hopes kind of diminish each day we don’t hear from her,” the police chief said.
