River Subs, a franchisee of restaurant chain Subway in Texas, has filed for Chapter 11 bankruptcy after losing a $3 million wrongful death lawsuit last year.

The company, which operates 48 restaurants, is seeking to reorganize during the process but did not state the reason for the filing. 

The firm generated less than $30 million in sales last year and employs 454 workers, Restaurant Business cited court documents. Its assets and liabilities were listed at between $1 million and $10 million. 

Martha Jordan and Cathy Amato, who founded the company alongside Rick Riley in 1991, will continue to lead the business during the filing.

Last year, River Subs lost a wrongful death lawsuit filed by the family of Marisela Cadena, a manager at the franchisee who was fatally shot by her ex-boyfriend outside a restaurant.

Cadena’s family members said River Subs failed to implement proper security measures after denying her request to transfer to another branch three days before her murder.

Subway has closed about 7000 stores over the past nine years, but remains the most prolific restaurant chain in the US with some 20,000 locations, according to Restaurant Business.
