One person is dead after a fire at apartment building in Derby on Sunday morning.
The fire was reported at 204 Derby Ave. around 7 a.m.
Family members confirmed 46-year-old Nilda Ruiz, a mother, died in the fire. The woman's name was not released by authorities.
“I heard an explosion, and I ran to the back room and I told my boyfriend,” Rosalia Ruiz, who is the victim's sister, said.
Ruiz said she feared that blast came from her sister Nilda's nearby apartment building, so she quickly rushed over to it.
"I saw the flames,” Ruiz said.
Ruiz said she desperately called and stared at the second floor apartment window. Nilda's children live elsewhere.
“When she came out and it was just flames and black smoke that came out of her window,” Ruiz said.
Ruiz said she was powerless and she knew it.
"I broke down and started screaming,” she said. “[There’s] nothing I could do."
Police were rushing to save others such as Sandy Rennie and her family.
“We opened the door and cops were literally ripping us out of the house," Rennie said.
Five families were displaced by the fire. The American Red Cross is assisting those families with a temporary shelter.
Multiple fire departments including Orange and Ansonia provided mutual aide to Derby Fire Department.
Derby's chief told Eyewitness News it took nearly 30 minutes to get the blaze under control.
People, pets, most everyone was safe expect Ruiz.
The cause of the fire is under investigation. State Police Fire Marshal is assisting in the investigation.
