Upper Gwynedd Fire 'Accidental,' Source Unknown, Says Fire Marshal

Upper Gwynedd Township Fire Marshal Jeffrey Tomczak could find no specific point of origin for the fire that damaged 189 and 185 Wissahickon Avenue twin home on the night of Mother’s Day.

The May 12 fire displaced a single mother and her two sons.

According to the marshal’s report, there “were two items that were unable to be ruled out as potential causes of the fire.”

Tomczak reported that there was no malice intended on the part of any involved parties.

This means the origin is “undetermined” and the cause of the fire was accidental, according to the report.
