Authorities say a fire in Jackson Township that claimed the life of a woman and injured three other people has been ruled accidental.

According to the Ocean County Prosecutor’s Office, police and fire department personnel were called to a home Thursday around 8:45 p.m. and found the structure engulfed in flames.

Authorities say Salvacion Elyea, 82, was pronounced dead at the scene. Another person jumped from the second story and had minor injuries. One police officer was treated for smoke inhalation and another for minor injuries.

Prosecutors say an investigation determined the blaze was caused by “a kerosene heater being located in too-close proximity to a combustible liquid.”
