Who is Steven Williams, the man who confessed to killing a Hobe Sound mom?
Martin County Sheriff Lt. Michael Dougherty has been working on the case since the beginning.
He said Tricia Todd's ex-husband, Steven Williams, was cooperating and willing to help, when they first talked.
"He even donated to her (Facebook page, Search for Tricia Todd) to try and show he didn't have anything to do with it," said Dougherty.

"The stories started off when he actually acknowledged she had died in his presence that she overdosed. Then he went into she didn't overdose, she overdosed because she wanted to get back at him, which didn't make any real sense," said Dougherty.
