Police believe they're finally closing the unsolved murder of Lindy Sue Biechler that dates all the way back to 1975 thanks to a little help from an airport coffee cup.
Nothing excites people's curiosity quite like a mystery and if the rise of true crime has taught us anything, it's that it doesn't really matter how morbid that mystery is.
Over the years, some people have proven that no matter how old a cold case is, they're still up to the challenge of solving it.
Granted, not all of these self-proclaimed detectives are successful, but the ones who are managed to spot a small detail that investigators missed in the years or even decades since the crime occurred.
And while those tiny details have proven the innocence of some unfortunate suspects, there are just as many stories of someone who thought they got away only to be undone by what seemed like a minor indiscretion.
In one case, all the suspect had to do to finally get himself caught was enjoy a cup of coffee.
