Murder victim’s DNA found on suspect’s alleged belongings:
DNA evidence was presented in the trial of Scott Dyleski yesterday, which the prosecution says links him to the crime scene of Pam Vitale’s murder.
Contra Costa County Sheriff’s senior criminalist David Stockwell told jurors Tuesday that DNA on a face mask, a glove and shoes that Dyleski’s mother had testified belonged to the teenager matched Pamela Vitale’s profile to a certainty of one out of 13 quadrillion Caucasian females.
For the math impaired, that’s this many. 13,000,000,000,000,000. So there is a 1 in 13,000,000,000,000,000 chance that the DNA found on Dyleski’s clothes was not Pam Vitale’s
A possible match to Dyleski’s DNA also was found at the crime scene in traces of blood on the bottom of Vitale’s right foot, Stockwell said, although one out of 43,000 Caucasian males could have the same DNA profile.
Which would mean if it wasn’t Dyleski then someone who has a 1 in 43,000 chance of having the same DNA profile of Dyleski did it. Possible, but not probable.
Dyleski’s DNA, however, was not found under Vitale’s fingernails, and none of her DNA was found on a knife that his mother, Esther Fielding, turned over to authorities, Stockwell testified.
Not surprising since he was wearing a face mask. However, he still could have had scratches on his face.
On cross-examination by deputy public defender Ellen Leonida, Stockwell said one of the DNA samples from the inside of the glove does not match the defendant.
But is that enough to cause reasonable doubt? I don’t think so.
