Preston Taylor doesn't want to share a campus with David Cash Jr., the man who admits he did nothing to stop his friend from strangling a 7-year-old girl at a Nevada casino last year.

Taylor, a senior at the University of California, Berkeley, is disgusted that Cash didn't try to stop his friend - and that school officials say there's nothing to be done about it."It's an embarrassment that the university isn't doing anything," says Taylor.

He's not alone in his disgust. Cash has been publicly scorned, even spit on at a convenience store. Some fellow students have launched a campaign of public humiliation and private snubs aimed at getting him to leave school.

Not everyone, though, is pressing the 19-year-old Cash to get out.

He has broken no laws. Nevada has no good Samaritan law, and authorities say Cash won't be charged with anything. Nevada prosecutors and UC Berkeley administrators have made it clear they won't move against him.

His friend, Jeremy Strohmeyer, pleaded guilty Sept. 8 to murder, sexual assault and kidnapping Sherrice Iverson in May 1997.

While Strohmeyer has languished behind bars, the spotlight has glared on Cash. Two radio show hosts from Los Angeles chartered a bus to bring demonstrators to Berkeley in August.

"You do not need this guy in your school," Sherrice's mother, Yolanda Manuel, told hundreds of protesters. "You do not need him sitting next to you in class."

Cash, a sophomore majoring in nuclear engineering, later became the subject of a student government meeting at which a largely symbolic resolution asking him to leave passed on a tie-breaker vote. Student government President Irami Osei-Frimpong vetoed the censure.

"I do not believe it's the organization's right to cast moral judgments without benefits of due process," he said later.

Taylor, who as executive vice president of the student government group broke the deadlock, said students have few options in dealing with Cash.

"A lot of students are trying to find ways to express their concerns, but there really are none," he said. "What I hear is a lot of people stare at him, give him mean looks, don't talk to him."

Some are furious that Cash is taking up a slot at highly competitive Berkeley.

"I am totally giving him the silent treatment. I don't even want to have contact with him at all," said Candice Blagmon, a freshman who lives in the same dormitory complex as Cash.
