MORRISTOWN -- Authorities released the identity of the woman killed in a residential fire on Pine Street Monday night.

Kelly Smith, 31, a resident of one of the five apartments located at 15 Pine St., died during the fire, Morris County Prosecutor Fredric M. Knapp and Morristown Police Chief Peter Demnitz said in a news release.

At about 11:29 p.m., police and fire officials responded to a fire at the multiple-family dwelling, which had 11 people residing in it at the time, they said.

Smith's manner of death was determined to be accidental by the Morris County Medical Examiner's Office, Knapp and Demnitz said. She was found on the third floor of the building, according to Morris County Prosecutor's Office spokeswoman Denise Arseneault.

The fire originated on the lower level of the residence, and it does not appear to be suspicious in nature, Knapp and Demnitz said. They also said they don't expect any criminal charges will be filed.

Authorities didn't indicate Smith's specific cause of death in the news release.

Seven people who lived in the building are receiving emergency assistance in the form of food and clothing from the American Red Cross, according to American Red Cross spokesperson Diane Concannon.
