The Danbury City Council voted this week to hire the Ventura Law firm to represent it in potential litigation against some of the nation’s largest pharmaceutical companies for their alleged role in causing the opioid crisis.

Ventura Law’s Chief Executive Officer Augie Ribeiro told the Connecticut Law Tribune Friday that he expects to file a lawsuit in Danbury Superior Court by year’s end. The council’s move comes on the heels of two other law firms—Scott + Scott and Simmons Hanly Conroy—filing opioid lawsuits on behalf of more than 20 Connecticut municipalities over the past six months.
