Hit a pig with my car

I was driving home from my buddies place which is out in the middle of nowhere. I've done this drive a dozen times so I wasn't paying much attention to the road, giving glances to my phone. Saw the street light ahead about a mile or so down the road when BOOM, I hit something. I stopped my car and looked down the road to see a pig laying on its side. I checked my car and didn't see any real damage. I looked around and saw no street or farm signs or anything of the like. The pig then tried to get up but fell down again. He looked at me with a "help me" look in his face but I was no vet and wasn't planning on throwing him in the back of the car. He looked rattled but seemed to have no serious injury to him (no blood, head was intact, no missing limbs, etc), so I decided to get out of there.

The next day we get a knock at the door and my wife answers the door. She yells to me, "babe the cops are here for you..."
I go to the door and one of the cops says, "hello sir I'm officer White and this is officer Smith, we would like to ask you a couple questions."
"Okay, how can I help you officers?"
"Well, you can start by telling me where you were last night"
"I went to my buddies house out by the ranches to play some cards and came home" I said.
"Okay, do you drive a white Honda Civic with license plate ...."
"Yes" I said, "what is this about"
"Sorry sir but we have a report from a local farmer that you were involved in a felony hit and run with his pig. Unfortunately we are going to have to take you in"
I tried pleading my case by saying that there was no one around and that I looked for signs for someone to call but found none, but they didn't seem to care. They put the cuffs on me and I started to walk to their car. As I made the walk I looked at one of the officers, "sir, I'm sorry but how did this even come about? Who told the farmer that I had hit the pig? I don't understand. It was in the middle of nowhere, no one was around and it was night out."
I started to sit down in the back of the car and right before he closed the door he said, "the pig squealed"
