Internet/Mail Fraud

[River99]

I was wondering if there is a timeline for filing a police report for fraud? Here's the story.. Myself and at least 2 others were scammed for a dog online that didnt exist,(She was Good) The money was sent with Cashier's Ck's and Money Order through mail, Girl (23 yr old) finally confessed in an email, and then found out She had already spent the money, kept saying she would pay back,(We figured if she was in jail would never see a penny) finally wouldnt respond to email, disconnected phone ect..had to track her mother down in TX to get her to start paying anything to someone, The problem is she is on the 30 year plan, Wont give how much and when she can pay, stretches correspondense out for weeks, Is there only so long we have to file charges before she gets away with it? Any assistance would be greatly appreciated!! The Fraud was commited in the state of Florida. With CA and MD being the victims states. Thanks!
