In 1910, 25 year old Dorothy Arnold went out to shop for a dress for her sister's debutante ball. And then she disappeared into thin air. 112 years on, and there has never been so much as a single clue as to what happened to Dorothy. Did she run away to start a new life? Did she die in a botched abortion? Was she abducted off the street? Maybe one day we'll find an answer. 

In September 2001, a man walking across Tower Bridge in London spotted a human body floating in the Thames, something investigators would soon discover to be just the torso of a young boy who seemingly had been victim of a ritualistic murder. Despite many leads and close calls over the years, 21 years on and Adam still doesn't have an identity, and police don't have their perpetrator.

In 1944 a fire at the Ringling Bros and Barnum and Bailey circus in Hartford, Connecticut led to the deaths of 168 people, of which 5/6 people still remain unidentified. As well as finding these identities, investigators have battled for decades to find the true cause of the fire - was it a carelessly discarded cigarette or something more nefarious?

In 1988 in New Bedford, Massachusetts 11 women went missing over the course of just 6 months and over the coming year, 9 of their bodies would be found alongside major roads leading out of the city. Despite a number of good suspects in this case, investigators were slow to realise something was going on under their noses and therefore the case remains unsolved to this day.

In 2014 the Broaddus family bought their dream home in Westfield, New Jersey. All the preparations were made to begin some serious renovation work before they moved in when an anonymous letter arrived from someone who referred to themselves as 'The Watcher'. Thinly veiled threats were made to the family's children and this person professed to be part of a long line of people watching the house, generation after generation. Who were they and what was their motivation?

Today we're talking a look at the Hays Code, a list of 36 'don'ts and be carefuls' for movie studios starting back in 1934 that changed the face of Hollywood forever. Ever wondered why Golden Age Hollywood films are so PG? Why even now queer people characters are hard to come by in films? Here's your answer!

On 19th September 1990, the body of a teenage girl/young woman was found by workers on the side of the I-40 in Hillsborough, North Carolina. She had been there for less than a week, and despite a couple of witnesses coming forwards enabling police to piece together her final hours, she's never been identified. Who is New Hope Jane Doe and who is responsible for her murder?

In the 1960s, a serial killer roamed the streets of West London, hunting for poor sex workers to be his next victim. Each woman would be found nude or partially nude with teeth missing and covered in paint splatters. But despite extensive investigation and many suspects over the years, the killer nicknamed Jack the Stripper has never been apprehended. 

65 years ago, the body of a young boy was found on Susquehanna Road in Philadelphia. Despite one one the biggest searches in state history, and becoming one of the most infamous Doe cases of all time, the boy has never been reunited with his identity, nor given justice for his murder. Genetic genealogy might mean we're close to answers in this case, but spreading the word is always helpful.

Police insist that in August 2014, 22 year old Jake Latiolais ended his own life by jumping over the edge of the Horace Wilkinson bridge in Baton Rouge, Louisiana, however there has never been any solid evidence to support this theory - and no proper investigation was ever conducted. I've worked closely with Jake's mum, Tina, to bring his story to you today and try to spread the word.
