Calvin J. Williams pleaded guilty to sexual abuse, just as attorneys were preparing opening statements for his trial in Cattaraugus County Court.
The plea came after two days of jury selection. Williams, 36, of West Valley pleaded guilty to first-degree attempted sexual abuse. The victim was a woman and the crime occurred June 22 in Yorkshire.
He was indicted by a grand jury last year on charges of first-degree rape and unlawful imprisonment. Sentencing is scheduled for May 1.
