Joe Hunter

The results?

Her DNA was found on the sash, along with an unknown male, not Mark Lewis.

Was anything done to investigate that further?

Could it have been anybody else associated with Mark Lewis?

CODIS is the FBI's criminal DNA database.

Captain Harris says the anonymous male DNA has never been identified.

Darrell Snedeker, former church member and retired Solano County deputy sheriff, says things were missed.

And a team of experts was about to come forward for the Hunter family, offering help and hope.

This is Dr. Bill Smock.

He is sure that Joanna was murdered and says he can prove it.

In 2023, Smock was hired by the Solano County Sheriff's Department to look at the case.

He is a medical doctor who, by his count, has reviewed thousands of autopsies and examined forensic evidence for police departments across the country.

Smock also has been an expert witness in high-profile cases, including testifying against Derek Chauvin in the 2021 George Floyd murder trial.

And where the Solano County Sheriff's Department saw a bathrobe sash, a note and a suicide, Smock saw something else, something new.

But because he was required to sign a nondisclosure agreement, no one outside the sheriff's office saw Smock's report.

Here was everything the hunters had been looking for, but they did not even know the rope existed or how Smock made his determination.

Smock was eventually released from the NDA and was able to show us using mannequins and red paint.

Smock says Joanna's neck had two different ligature marks.

One is from the sash and one is from the marine rope.

Here is the autopsy photo, which we are showing you with the family's permission.
