Advice scam?

[Perrine POUILLET]

Hello,

I have been approched in an investment group in the bay area by someone willing to invest my money in flips. this person (Keith Wilson from Tribbecca Properties) talked to me into investing $100,000 in a flip in San Jose in October 2007 for a 50% of the profits. After signing a contract with the help of an attorney, I wired the money to a company incorporated in Nevada ( Lone Ceddar Corporation). He was supposed to reimburse the money invested by Dec 1st 07 if he had not closed on the house. I know the house was never purchased and I don t have any news from this Keith Wilson who does not answer emails or phone calls. I had a warning letter sent to him through my attorney in Jan 08 to which he answered that he was trying to find some money to reimburse me. No news since.
Before launching a lawsuit, I would like to know what legal ways I have get my money back ( like puting a lien on his house or whatever action that would put pressure on him, quickly)

Thanks in advance
