A new report urges legislators to end the use of anonymous shell companies, to help law enforcement fight opioid trafficking. The report, by the nonprofit group the Fair Share Education Fund, says requiring all companies formed in the United States to disclose their owners would allow law enforcement to curb drug trafficking.

The group said criminals are easily able to launder drug trafficking money through anonymous shell companies, making it difficult for law enforcement to make cases against the traffickers.

The report describes 10 cases in which anonymous shell companies were linked to opioid trafficking, according to The Hill.
