Federal authorities in the United States have issued several prison sentences following various financial fraud investigations.

In mid-September, two women received sentences for distinct schemes. In New York, Nahtahna Castner was sentenced to 48 months for wire fraud and identity theft after defrauding an elderly neighbor of approximately $252,672. In New Jersey, Brigette Miller-Levy received 24 months for a Paycheck Protection Program (PPP) loan fraud that resulted in a taxpayer loss of $882,777.

Shortly thereafter, additional sentences were handed down for larger-scale operations. Chanise Coyne of Michigan was sentenced to five years in prison for a $4.6 million child modeling fraud scheme, where she used fabricated documents to divert funds toward personal spending. In California, Iris Rabaya Au received an 18-month sentence for failing to report $2.6 million in income linked to a cryptocurrency enterprise that involved paying corrupt Los Angeles County Sheriff’s Department deputies.
