ST. PAUL — Prosecutors have charged four people in what authorities call a “massive” fraud scheme in the Twin Cities involving public benefits.

The charges allege a husband and wife from Fridley and two accomplices duped the state out of about $4 million by falsifying work records at their home health care and child care businesses and funneling some of that money into another family-owned business.

The Ramsey County Attorney’s office filed 96 felony counts against the suspects after a two-year investigation.

Charged are Yasmin Ali and her husband, Ahmed Aden Mohamed; Joshua John Miller of St. Paul; and Jordan Christopher Smith of Cottage Grove.

According to the criminal complaint, Ali faces the most charges — 52 felonies — and appears to be a key leader in the fraud.
