KENTWOOD, Mich. (WOOD) — Kentwood fire investigators say it appears that the cause of the house fire that killed a 12-year-old girl and a 19-year-old woman was accidental.

Fire crews were called to the home on 48th Street between Division and Eastern avenues around 3:30 a.m. Monday for a report of a fire.

Ashlee Duran, 12, and Nety Chavez, 19, were pronounced dead at the scene. Chavez had recently come to Michigan from Mexico to visit family, a family friend told News 8.

They died because of smoke inhalation, the Kentwood Fire Department said in a Tuesday release.

Nine other people were inside the house and were able to escape the fire, according to the fire department. Officials originally said six others had escaped.

Fire officials say a space heater was found near where the fire started and they are investigating for possible electrical issues.

The family will be holding a vigil for Duran and Chavez at the house at 7 p.m. Tuesday. A GoFundMe has been set up for funeral expenses.
