Davis said he attacked Mrs. Robinson with a bleach-filled syringe and then a knife so the threesome could stay together. Whispel said at one point, Valessa straddled her mother's body to help hold her down. After their arrests, all three drew crude maps to Mrs. Robinson's body. Still wearing her peach nightgown and gold crucifix, she had been stuffed inside a plastic garbage can and dumped in the woods a few miles from her home. Juries are instructed not to consider what happened to a body after death.
Defense attorneys question whether that's possible, especially in extreme cases.
Davis was found guilty last year and sentenced to death. Pretrial testimony indicates that the effects of LSD and Davis' admission that he did the stabbing will be key in Valessa's defense. Valessa, who cannot be sentenced to death because she was only 15 when she was arrested, faces life in prison if she is convicted as charged. All rights reserved.
