something out of the ceiling is the day you see the gun? yes. behind the tile, likely prosecutors say where he kept the .32, one of the two guns used that night. there was only one person that we heard about that would have an interest in that ceiling tile and that s the guy that maybe left a gun up there that he don t want the cops to find. and as for the dusty shoe print, not definitively serrano s, but much like one he once owned and experts examined. the wear pattern is consistent with the shoe that stepped on that vinyl chair in december of 1997? absolutely. prosecutors knew they would have to shred serrano s alibi that he was in atlanta for a business trip and not in florida for the lethal business of murder. people would go to atlanta. they would find him on the videotape. he would be alibied and nobody would ever look any further. and that would be the end of it. in terms of being diabolical, that s a pretty good alibi.
