Fire officials: N. Portland house explosion caused by 'large concentration of butane'


Portland Fire & Rescue officials say the house explosion in north Portland was caused by butane coming in contact with an ignition source.

Firefighters were called to the scene on a report of a house explosion in the 6400 block of North Kerby Avenue around 3 p.m. Monday.

The home was completely destroyed and at least one home was on fire when crews arrived. Firefighters worked quickly to contain the blaze, but multiple factors such as a damaged gas line and downed power lines hindered their efforts.

Matthew McCrann, 42, was found at the scene and was rushed to the hospital with life-threatening injuries. Unfortunately, he did not survive.

A second victim, 68-year-old Richard Cisler, was found in the debris of the home late Monday.

Portland Fire & Rescue investigators determined that the explosion was caused by a large concentration of butane coming into contact with an ignition source.

PF&R said the homeowner was attempting to produce butane hash oil. The ignition source has not been determined.
