For armchair detectives, knowing all of the ins and outs of famous—or infamous, rather—cases comes with the territory.
Whether you've scoured the internet for details on the Manson family, John Lennon's untimely death, or think you can recite the facts from the first season of Serial better than Sarah Koenig, there's always more to know.
But instead of reliving the tragic crimes themselves, let's delve into the aftermath of several headline-making events and get an update on those who are currently behind bars…and are desperately trying to be released.

Charles Manson: Now 81, the convicted criminal and leader of the 1960's commune has repeatedly been denied parole—12 times in fact. Manson, who is serving a life sentence for seven murders, even told a California prison psychologist that he's a "very dangerous man" back in 2012. This ultimately lead to his most recent denial of parole by a California parole board.

Adnan Syed: The Baltimore native is currently incarcerated for the murder of his ex-girlfriend Hae Min Lee. Syed was convicted of first degree murder during his second trial—his first resulted in a mistrial—and was granted yet another trial in July 2016 after his original attorney was "rendered ineffective assistance when she failed to cross-examine the state's expert regarding the reliability of cell tower location evidence." Only time will tell what is in store for Syed's future.
