The Case of Stephanie Lazarus

The chance that the bite on Sherry's arm was from a different person than Stephanie Lazarus was over 402 quadrillion to one. They had her under surveillance for two weeks before they got their chance. A detective watched as she took her last sip and walked within three feet of him to put it in the bin. He didn't take his eyes off the bin as he waited for Stephanie to walk out of his field of vision. Then he approached the bin, picked up the cut by its base, and put it into an envelope. 48 hours later they got the result. The DNA was a clear match.
