Engine will not crank and oil pan shattered

So I drove through water and the car stalled out. So while on side road right after this happened I had tools so I pulled plugs dried them dried out air intake and left air filter out. With plugs still out cranked the engine to get water out from pistons it cranked but while cranking it stopped cranking suddenly with a metal hit noise but not like a rod just a clunk. It stopped cranking and has stayed with starter at least engaging the teeth but engine wont turn. I decided to give a shot in the light tomorrow and pushed car into a parking space. I noticed that looked like oil which it ended up being like maybe 2 cups worth started going over where it may have came from and noticed to my amazement my pan is not just cracked but in a lot of pieces. Now this had to have happened in the water because the amount of oil when I pushed the car but there was no noises it just stalled. Any ideas? Please help. Piece of pan in engine maybe engine doesn't seem seized. Starter bad or still wet and grounding out? Is my engine ruined and how did oil pan break so badly?
