CLAIRMONT: Blood from murder suspect's sister found in drive shed
..... But there was something in the first drive shed.
"It's a concrete floor with dirt on the surface of the floor. There was some darker staining."
It tested positive for blood.
In his lab, he broke the sample down further. It was human blood. Female blood.
Then he compared it to a DNA profile he had generated of Rhonda, using the pulp from a tooth removed during her autopsy.
In January 2000 he reported that four samples taken from within the stain on the drive shed floor "matched the profile of Rhonda Borelli."
The probability that it could be someone else's blood was 1 in 62,000, according to the tests available at the time.
On July 4, 2013, the samples were checked again using the latest testing methods. Now the chance that the blood belonged to someone other than Rhonda was one in 1.58 quintillion.
"I must confess, I don't even know how many zeros it's got," Newman said when asked what a quintillion is. "It's more zeros than you have on your calculator."
What science can't say, Newman told the jury, is how much of Rhonda's blood is within the stain. Or when the stain was made.
