FAQs
- What crimes does the documentary cover?
The documentary explores the murders of Samantha Class (1997) and Alena Grlakova (2018), both of whom were killed by Gary Allen, and the investigation that eventually led to his conviction. - Who is Gary Allen?
Gary Allen is a British convicted murderer now serving a life sentence with a minimum of 37 years for the murders of Samantha Class and Alena Grlakova. - Why was Gary Allen able to avoid justice for so long?
Allen was originally acquitted of Samantha Class’s murder in 2000 due to a jury verdict, and legal restrictions on retrial under the old double jeopardy law meant he could not be tried again—until after the law changed and new evidence came forward years later.
