[digdug]

okay the exact story is that my friends and i were having a party at his house about a mile from my home, i took my friends truck home on the way i hit my neighbors mailbox, so i stopped at my dads, who lives about 500 yards from my neighbor, because he knows my neighbor better then i do. while i was there my neighbor showed up to ask if i was okay, of course i apologized and offered to pay for the mailbox, she said that was fine and i paid her money for mailbox and then had them replaced the following day. after all this i had to call my friend to let him know the bad news about his truck, i was sitting at my dads house for about an hour. during this time we had a couple of mixed drinks, then a knock on the door and it was the police someone had called them after i had hit the mailbox, the officer asked if i had been drinking i told him i had been drinking with my dad in the house, he started to give me tests and i refused because i had been drinking in the house, so he handcuffed me and took me the police station where i refused to take the breath test, he then charged me with dui, hit and run, careless operation of motorvehicle, my neighbor signed documents stating we had already resolved the mailboxs before the cops got there, so i just want to know if they have a case on any of the charges
