The investigation continues into the cause of a Friday night two-alarm fire that left seven people homeless and one dog dead.
Waco firefighters saw flames coming from several upstairs windows of the two-story house when they arrived at 401 North 16th Street about 10 p.m. Friday.
Because of high heat and heavy fire conditions, those first arriving immediately called for a second alarm for additional help.
A steep roof made fighting the fire particularly difficult.
A search confirmed that all occupants were out safely, but a dog was found dead in a closet of the room where the fire is believed to have started.
The fire gutted two upstairs bedrooms and a bathroom with two adjacent rooms and walls of a staircase also heavily damaged.
