Got ripped off, Advice please.

this may be a bit long, and i appreciate you taking the time to read this. I decided to post this here first, because after lurking for some time you all seem to have experience in dealing with this.

short story:
bought 1996 impala SS, claimed to have 88k miles, broken odometer, fixed it actual 149K miles.

long story:
recently came into some money, paid off some debt, and bought a dream car. wanted a reliable daily driver so i settled on an impala SS. located on on the impalassforum, and went over to illinois to look at it. Guy claimed it was his aunt's recently gave it to him, he's selling. Also claimed speedo recently went out, had about 81,250 when it did. car ran and drove good, but had some quarter damage. ended up paying $6,800. get it home, fix the odometer, and car has 149,xxx miles.

call seller, claims to have no idea. Later says he's not responsible, sold as is, it doesn't matter in illinois.

Now, i have the title where he wrote 88,200 i have a bill of sale 88,200, i also have a email, and have found postings on multiple BB's where he claims 88,200.

i have contacted peoria police and they say it is a civil matter. How is this not fraud? states right on the title "federal and state law requires that you state the mileage in connection with the transfer of ownership. failure to complete or providing a false statement may result in fines and or imprisonment."

anyways where do I go from here to get my money back? Thanks
