Learn about this Garden Talk

In homicide cases that remain unsolved after one year, only 5% will ever lead to an arrest.

Investigators reviewing a cold case often find themselves battling on multiple fronts: evidence can be missing or lacking context; the memories of witnesses have often faded; and frequently misinformation and conspiracy theories arise in the vacuum of a cold case that muddy the water for police and forensics experts.

How do investigators sift through multiple hypotheses to find the truth?

Prof. Jim Fraser is one of the UK's foremost forensic experts - he quite literally wrote the handbook. Through the lens of one specific and highly unusual case, Jim joins us in The Garden to give a fascinating behind-the-scenes peek into how investigators extract information from chaos and distinguish fact from fiction in a complex case review.
