The Miami-Dade Police Department, Economic Crimes Bureau is investigating several incidents that involve a scheme to defraud innocent people.  According to investigators, the subject, Doris Yesmina Ortega, would offer a business proposition where they would invest thousands of dollars in musical events and/or concerts with an even split on the profits.  Some of the investments were in excess of $40,000.  The scheme consisted of the following, an initial check was provided to Ortega with specific follow-up instructions.  Ortega would then provide the victims with a check for their share of the profit and would request them to withdrawal a portion for additional investments.  Once the victims received notification from their bank that the account and/or check was not valid, they would attempt to locate Ortega but she was nowhere to be found.  Upon speaking with several individuals, investigator have also learned that Ortega has defrauded many undocumented immigrants.  She advised them that she was a federal government employee and she can obtain legal immigration status in the United States.  The victims would provide an agreed amount of money as a fee for her services. Once time had elapsed, the victims made contact with Ortega to follow-up on the status of their case and Otrega would then demand additional monies.  Once the victims advised that they did not have the money, she would then threaten them with deportation.  Having learned this, investigators are seeking victims of this crime to come forward so Ortega may face additional charges.
