Lesley Herring was known to be a solid, reliable person who always showed up - so when one day in February 2009 she failed to turn up for work, her family knew that something was seriously wrong. What followed was a hunt, not only for Lesley but also for her husband Lyle, investigators following a trail of red herrings he'd left in his wake.

A few years ago Thomas Chan consumed magic mushrooms and went on to attack his father, arguing the defence of automatism in court: he wasn't responsible for his actions whilst under the influence. This, and the case of Sullivan, opened up a can of worms in Canadian law. 

This week we're going to be looking at some updates in cases that I've covered in the past, including Alicia Navarro, Lady of the Dunes, Nude in the Nettles, Paige Johnson and more. 

Throughout the 1970s and 80s, the bodies of a number of women were found alongside major interstates from Virginia to Missouri. Investigators soon began to connect the cases, as all the women had one thing in common: they all had red hair.

In the 1960s, two couples were driving near Point Pleasant, West Virginia when they came across a creature that they could only describe as 'not-human', 7ft tall with 10ft wide wings and glowing red eyes. They reported it to the local authorities, and since then countless people have reported a similar creature, some think it is a harbinger of doom. But if the mothman exists, why is there no solid evidence?

In 2001, a missing persons segment was aired on Mexico's Canal 5 and for some reason people on the internet deemed that the photo of missing Selene Delgado Lopez was fake... and from there, you won't believe where this story goes.

On 29th October 2004, a woman got in the lift at the Wembley Point building in London and took it all the way up to the 21st floor. Once there, she calmly opened a window and jumped out, her body soon being found in the river down below. Almsot 2 decades on and she has still not been identified, despite a number of interesting clues being left behind.

The 1800s were a time of great migration within the USA, with families packing their entire lives into wagons and setting off on the treacherous journey. Lansford Hastings managed to convince the Donner-Reed party to try out a new route, one which was apparently shorter than the usual - they'll reach California quicker! But things went terribly wrong, and the party were forced to do things to survive that no human should do.

In April 1998, Traci Pittman Kegley failed to turn up home to her parents house, causing them to search for her through the night. The next morning, her car is found abandoned on the side of the road with her 2 year old daughter in the back, entirely unharmed. There's never been a single sighting of Traci since.

In 1980, Jessie Earl was due to come home to visit her parents but when she failed to arrive her mother headed down to her flat in Eastbourne to ensure Jessie was okay - only finding an enduring mystery. 9 years later, Jessie's body would be found but their battle would be far from over.
