The State Fire Marshal’s office says the Saturday morning fire was an accident caused by a faulty extension cord. Killed in the fire were 39-year-old Crystal Vickrey; 19-year-old Brittney Newsome, 12-year-old Kaden Newsome and 20-year-old Tiara Schwab. Autopsies reveal that smoke inhalation was the cause of death in all four.

Two people were able to get out without injuries. Their names have not been released.

Cordova is a village of fewer than 150 people that’s about 30 miles (48 kilometers) west of the state capital of Lincoln.

The University of Nebraska at Kearney released a statement identifying Brittney Newsome as a first-year student at the school.
