MOBILE, Ala. -- Preacher Anthony Hopkins' stepdaughter has said she was sexually abused by Hopkins starting when she was 11, but Hopkins testified today that they did not have their first sexual encounter until March 2008.

It was then, Hopkins testified in his rape and murder case, that his eldest stepdaughter, who was 19 at the time, approached him in the living room wearing a "chocolate negligee."

"From that point, I was tempted and I yielded to the temptation," Hopkins testified. "As a result, she got pregnant."

Hopkins is accused of murdering his wife and storing her body in a freezer for 4 years, even hooking up a generator to make sure the freezer never lost power in a hurricane or other storm. The 39-year-old began testifying in his own defense this morning as he faces charges of murder, second-degree rape, second-degree sodomy, second-degree sex abuse and incest.

Prosecutors say he killed 36-year-old Arletha Hopkins in December 2004 after she learned that her husband had sexually abused the stepdaughter.

Hopkins has denied killing her, saying he does not know how she died, but that he tried to keep her body preserved because he could not stand the thought of her decomposing. He said his family continued to live their life together, preaching and going to work, after his wife's death.

While the stepdaughter told jurors that Hopkins jumped up and down on the body to make it fit in the freezer, Hopkins denied doing that.

He said his wife's body "fit snuggly," though "I did press the freezer down."
