A federal judge in McAllen has ordered Alejandra Resendez of Weslaco to remain in custody pending a detention hearing.
Prosecutors on Thursday did not have information on an attorney for Resendez, who was indicted last month on two counts of mail fraud and two counts of identity theft.
Investigators say Resendez, who appeared in court Wednesday, used Social Security numbers and other private information from unaware clients to file for unemployment benefits in their names. Benefits were sent on debit cards that Resendez allegedly used to get cash.
Investigators say the scheme ran from mid-2010 until early 2013.
