Long time Regional Apt Manager here.
1) Found one while clearing an overgrown lot near a Jax, FL community — it'd been there a while.
Yes, was an unsolved murder.
2) Was missing a resident in a mid-rise in a Gulf Coast city (for a week); other res's complained of a smell, some identified it as known to them.
Sure enough, the guy shot up Lortabs and sliced his femorals in the bathtub. Family accused us of stealing 'hidden' money. And then, the usual 'died peacefully in sleep' anyone in this business knows.
