Shoplifting Ring Bust in San Diego

Jun 26, 2025

Overview

A San Diego County woman, Michelle Mack, has been arrested and accused of leading a national shoplifting ring targeting Ulta Beauty stores, resulting in millions of dollars of stolen goods being sold online.

Details of the Investigation

  • Michelle Mack is alleged to have led a theft ring targeting Ulta Beauty stores across multiple states since 2021.
  • The ring involved recruiting up to 12 people to steal from retail stores and ship items to Mack's post office box.
  • Mack is accused of selling the stolen goods via Amazon, making nearly $2 million in 2022 and about $8 million since 2012.
  • Evidence found during a December 6 federal raid included a large cache of stolen cosmetics valued around $350,000.
  • Shoplifters were reportedly provided with specific target lists, flights, rental cars, and hotel expenses covered by Mack.

Law Enforcement and Corporate Response

  • Initial investigation began with 12 suspects in Southern California Ulta thefts; two arrested individuals on the East Coast linked the operation back to Mack in California.
  • Social media communications were instrumental in connecting the suspects to Mack.
  • San Diego County District Attorney Summer Stephan highlighted the wider community and safety impacts of organized retail theft during Congressional testimony.
  • Ulta Beauty cooperated with authorities by providing investigative support and has a dedicated national team handling organized theft.

Unresolved Issues

  • It remains unconfirmed whether an earlier Ulta theft in San Marcos is connected to Mack’s alleged crime ring, as the DA’s office has not responded to inquiries from media.
