ARTICLE SNIPPET: "UPPER MARLBORO, Md. (AP) - Temporary lighting used in the attic of the old Prince George's County courthouse during renovations caused the fire that destroyed much of the 19th century building, county fire investigators said Monday.
Based on witness interviews and analysis of the building, fire investigators determined the electric lighting system sparked the blaze on Wednesday, according to fire department spokesman Mark Brady.
He could not say what specifically about the lighting caused the fire. However, the fire was ruled an accident."
