I'm local. Live about 10 minutes from family home, preserve et al.
Just to rein it in a bit, this preserve is IMO just a bunch of overgrown weeds. Nothing fancy. Small trails. Bird watchers. Ticks. Mosquitos. Dirt parking lot. Not a very sentimental place for suicide.
My official local opinion from the first second I saw this case on TV was "HOLY COW THAT'S A REALLY BIG HOUSE FOR A UNION GUY!" and in Dix Hills no less, a very affluent area. This is what actually made me follow the case. I knew something was up immediately. And then to find out the wife was unempolyed as well...
Also, IMO "You're important" means "Honey, you count. It's not just our huge house, our fabulous trips, and $$$$" And "Keep you safe" means from the IRS, Creditors, the divorce attorney.
Just sayin'
