Some good friends of my relatives who live in Northern Florida found this snake in their yard, fearing that it was vemonous, they killed it, but are concerned that there could be more. To me it doesn't look like a vemonous species. From the second pic it looks more like a water snake but I never seen a water snake with this kinda pattern and coloration, so I am not 100% sure,
The photos are graphic.
