BOCA RATON, Florida: A Florida woman who came forward on Thursday became the fourth in recent weeks to accuse Bill Cosby of sex abuse.

Therese Serignese, now 57 and a nurse in Boca Raton, said the television icon raped her in 1976.

Cosby spokesman David Brokaw did not respond to a request for comment. Cosby’s lawyer, in a statement released Sunday, criticized previous “decades-old, discredited allegations,” stating that “the fact that they are being repeated does not make them true.”

Cosby made no mention of the allegations Thursday during a benefit performance in the Bahamas for a women’s service organization. He stuck to his routine, including stories about his childhood growing up in the projects of Philadelphia. There were few empty seats in the house and a few people gave him an ovation when he finished his set.

Some in the audience said the allegations against Cosby remain unproven and they added that his performance was a benefit for what they felt was a good cause.

Dozens of Cosby’s television and comedy colleagues have either refused to comment or not returned telephone calls from The Associated Press in recent days.
