Just wanted to let you know.
If I were in your shoes I'd be all over the investigators. Just call in to the PD main line, tell them who you are and what case you're calling about and you will be connected to the right investigator. Ask when was the last time a search was conducted. As you know, lots of woods around Gainesville. It would be tough to find remains in there.
When I saw this thread bumped it reminded me of this case from a couple years ago:
Found Deceased - FL - Jason Winoker 52, from Tampa, Springhill Suites, Tallahassee, 17 Aug 2021
He was found a year later a short distance away from the hotel which he went missing from.
