there was a hit and run

Ok about like 3 something in the afternoon heard the dog barking and seeing something out of the blue this gray came out of nowhere with mess up front and no driver in the car it just rolled into the neighbor's grass still no driver I've could call the police but my mom stopped me and want my dad to call them. I was the one who saw the car and now the police is over here investigating of who's gray car is it but for real don't send a lot of police over here. Even the neighbors have saw the car and the drive bys didn't do anything just drive by and wondering who's car is it and why did they leave it there for.
