Investigators are looking for the cause of the fire that killed a woman and four children in a Seattle apartment. The fire department said investigators have no reason to believe Saturday's fire was suspicious.
The department also is trying to determine why the first engine on the scene was unable to pump water. The crew had tested the pump earlier that day without problems.
One woman and a child escaped the fire but others were trapped by flames .
The apartment is owned by the Seattle Housing Authority, and a spokeswoman said a smoke alarm did go off.
Never miss a local story.
A memorial for the victims is planned for 11 a.m. Friday at the Seattle Center’s Exhibition Hall.
