gun shots?

Early this morning, around 3 AM, we heard what sounded like gun shots coming from Leschi, near the water perhaps.  There were never any sirens so perhaps these were fire crackers.  Hard to tell.  If someone knows what these were, would love to know.

Update by scott: Police received many calls on this, and spoke to a man at 23rd & Jackson who reported seeing fireworks being set off by someone west of there, towards Washington Middle School
