No direct evidence but a ton of circumstantial evidence.
From Wiki:
“A single hair was the only piece of forensic evidence that was identified. The hair, matched through DNA comparison to hair from Laci’s hairbrush, was stuck to pliers found on Peterson’s boat.”
A single hair on a pair of pliers that can easily be attributed to transfer from Peterson’s clothing. No blood, no other signs of Laci. Just one hair.
My wife has never been to my office but plenty of her hair has shown up there over the years. Is that evidence of murder? Or is it just what happens when two people live together?
The rest of the case is built upon Peterson being a crappy husband who didn’t mourn his wife the way the police thought he should.
I would never want that POS in my house and I remain open to the possibility that he did indeed kill Laci. However, there is no evidence that he did. None. Nada. Bupkus.
