Arsonist who burned Seattle lumber yard pleads guilty

The arsonist who burned at least four Seattle properties, including a lower Queen Anne lumber yard last November, pleaded guilty Monday afternoon.

Matthew Daniel Hooper, 39, pleaded guilty to one arson count, listing all charged offenses, and will be sentenced to 89 months in custody with 18 months of community custody and a mental health investigation.

Police said they linked him to crime scenes through DNA, and charging documents say a charcoal lighter fluid bottle or evidence of the use of lighter fluid was found at three of the fires.

When he was arrested, Hooper was homeless and had at least 23 previous arrests.

The lumber yard fire happened Saturday, Nov. 10 in the 300 block of West Ewing Street. The multiple-alarm fire at Gascoigne Lumber spanned a city block, destroyed five buildings and caused explosions.

Hooper's sentencing is scheduled for 1 p.m. November 15.
