A mysterious sound resembling a thunderous explosion was heard around 8 p.m. on June 25 in the St. Helens area.
Curious citizens flooded social media with questions about the origin of the loud boom that some said shook homes and rattled windows.
According to St. Helens Police Chief Terry Moss, the first reports of the sound came in at 8:22 p.m. Moss said his department fielded 11 calls regarding the boom, mainly from residents on the west side of town.
The cause of the sound has not been determined. Moss said this time of year is marked by frequent firework and “loud boom” reports. Without more definitive information, Moss said the matter would be considered closed.
There was a viral reaction to the sound on Facebook, where reports of the boom were contentiously debated and numerous theories were offered. Everything from jet sonic booms to rock quarry blasting to North Korean missile testing and even more outlandish ideas were suggested. Some people heard nothing at all.
Many Facebook users suspected a modified firework or homemade bomb, but without evidence the citizen investigation made little progress. Anyone with information about the source of the sound should contact St. Helens Police Department.
The mysterious booms start shaing homes again… This time in Oregon.
