the detective from the attorney general 's office who had been in charge of the case testified that there was a turnout less than seventy yards from the bungalow , and that on the afternoon of 11 september , three pieces of evidence had been removed from that turnout : first item , two empty quart bottles of narragansett beer ( with the defendant 's fingerprints on them ) ; the second item , twelve cigarette ends ( all kools , the defendant 's brand ) ; third item , a plaster moulage of a set of tyre tracks ( exactly matching the tread-and-wear pattern of the tyres on the defendant 's 1947 plymouth ) .
