‘Simply loading the wrong type of gunpowder, loading too much gunpowder in there can take an open ended cannon and turn it into a bomb.’
Police confirmed a shard from the explosion was found 25 feet from the scene.
The Michigan State Police Bomb Squad, Gaines Township Fire Department, and Med Star Ambulance attended the scene.
Three parked cars and the garage where the
baby shower was being held were also struck by shrapnel.
Genesee County prosecutors are now said to be reviewing the case.
Police said the homeowner had bought the cannon at an auction and had fired it several times before. It’s suspected that the shrapnel came from the cannon breaking apart during the explosion, police said.
