Propane line cut and grinder ignition blamed for Annapolis house explosion

Investigators say a propane line was inadvertently cut during HVAC work, allowing gas to accumulate inside the Annapolis home; a metal grinder then sparked ignition, causing a fatal explosion that killed 76-year-old Linda Synowczynski and left a man seriously injured; the propane company did not contribute to the incident. Officials urge proper gas-handling by professionals and safety precautions if gas is suspected, noting the explosion was accidental and not propane company fault.
