Investigators on Monday will return to the scene of a fire at a one-story residence in Vancouver, Washington, that killed six people on Easter morning.
Authorities had initially said two people died in the fire about 1:30 a.m. Sunday. On Sunday evening, Vancouver police revised the number saying firefighters found the additional bodies after sifting through the rubble of the home.
Investigators do not yet know what caused the fire, but have not ruled out arson. Neighbors told CNN affiliate KOIN they heard a loud explosion just before the home went up in flames.
