The Scottsdale Fire Department released the investigation results on Monday of a fire that ripped through a townhouse during the weekend and killed a woman and her dog.
The investigator ruled that the fire on Sunday morning near 78th Street and Meadowbrook Avenue was accidental so there were no signs of foul play.

The flames moved into the home and then up the stairs. The woman tried to escape but was found on the ground floor near the stairs, the investigator said.
She was taken to the hospital where she later died.
She has been identified as 80-year-old Darla Johnson.
Firefighters found that poodle dead in the bedroom on the second floor.
Firefighters said there was a smoke alarm upstairs, but it's unknown if it was working.
