i was outside that night (i live in north beech grove) i heard it loud and clear but sorry, no screaming voices lol. i think we all know what it was by now. they still dont know what caused it and its slowly fading out of the news broadcasts, they seem to think it was intentionally set by someone. i heard two noises at almost the exact same time. i thought it was my neighbor kicking or banging on the wall since my music was halfway loud.
