The family of a woman killed in an Ethiopian Airlines accident last month plans to file a wrongful-death lawsuit against the airline, the aircraft manufacturer and the parts supplier linked to the crash that left 157 people dead.

The woman, Samya Rose Stumo, 24, was a grandniece of Ralph Nader, the consumer rights advocate and past presidential candidate. Lawyers representing the family said in a statement that they planned to file the suit on Thursday morning in Federal District Court in Chicago.

A number of other families are pursuing litigation against Boeing, Ethiopian Airlines and Rosemount Aerospace, the manufacturer said to be responsible for an aircraft part that may have played a role in the crash. In March, relatives of passengers on a Lion Air flight that crashed in October in Indonesia minutes after taking off also filed suit against Boeing; 189 people died in that accident. Both planes were Boeing 737 Max jets, which have since been grounded around the world.
