reporter: something else, something potentially huge. police found spots of blood in the bathroom the girls shared, a bathroom ashley used after theyy was murdered. so, did she just not see the blood? or did she leave it there herself? as you ll hear, detective ellzey used an old-fashioned strategy. he exaggerated the evidence, another way of saying he didn t exactly tell the truth, in an effort to get ashley to cough up the truth herself. you got to dig in people sometimes to really see where they re coming from reporter: sometimes you can throw them off stride and it puts them off their story. absolutely. i don t see how you can miss that big blood right here on the sink. i don t see how you can miss that. i don t see how you can miss the big deal of blood right here on the bathtub. i don t see how you can miss it all on the trash can. how do you do that? i didn t see the trash can. but i remember seeing the little splotch of blood on the sink.

had been growing that staph bacteria, there was a splotch around that spot of mold. in that splotch spreading out from the edges of the mold, there was no bacteria. that meant it occurred to him that that mold was killing the bacteria. in that moment, alexander fleming asked the key question hey, what s in that mold? fleming ended up writing a paper about his score of and published in 1929 to not much acclaim and not much notice. but years later, almost a decade later, scientists working at a lab at the university of oxford came across alexander phleflemi paper. they discovered this discovery about the mold killing off the bacteria looked like it might be promising. they started to work on it.
in 1928 in his lab at st. mary s, alexander fleming had a very fortuitous and ultimately world-changing encounter with dirty dishes. he had been working with a fairly nasty strain of staff bacteria in his lab when he found quite by accident that one of the culture plates he had been working with i guess had been neglected or somehow cross-contaminated. in any case, it had started to grow a bit of mold. under normal circumstances, that might be cause for regret. oh, no, this is spoiled, or you might be mildly grossed out. that would be cause for throwing that out or cleaning up that culture plate. but what fleming noticed that day in 1928 and what ultimately changed the world was on that culture plate which he had been growing the staff bacteria, there was a little splotch around that spot of mold.
