Day 20 testimony centered around DNA evidence found on Chad Daybell’s property

BOISE, Idaho (KIFI) — Day 20 in the triple murder trial of Chad Daybell continued Thursday in Ada County.

Testimony centered around DNA evidence found on Chad’s property where Tylee Ryan and JJ Vallow's bodies were found.

A shovel and pick ax were brought in. Evidence shows those were found on Chad Daybell’s property the day the bodies were found.

A forensic biologist says she collected blood and some possible human remains from the shovel and the ax.

She was able to get positive DNA results relating to the children from both the ax and the shovel.

Rob Wood: Did you compare this the DNA profile from this material with Tylee Ryan's sample?

Forensic biologist: I did.

Rob Wood: What were the results of that testing?

Forensic biologist: The DNA profile from this item matched Tylee Ryan. Iit is at least 604 octillion times more likely to see this DNA profile if Tylee Ryan is the source than if an unrelated randomly selected individual from the general population is the source.

Rob Wood: And can you say that number one more time"

Forensic biologist: 604 octillion.

Rob Wood: How many zeros are in an octillion?

Forensic biologist: An octillion Is 27 zeros.

DNA testing was also done on blond hairs that were found on the duct tape that was wrapped around JJ's neck and head.

The partial DNA profile was a match to Lori Vallow-Daybell.
