Attendees will also be able to dive into the harrowing and empowering journey of international bestselling author, Mary Turner Thomson, who will unravel the deceptions of bigamist Will Jordan.
Attendees will also hear from filmmaker and author Bexy Cameron who will be speaking with Kacey from the Cult Vault podcast about her life growing up in the Children of God, a notorious international cult active even in Scotland.
Also in attendance will be presenter of the hit podcast I Am Not Nicholas, Jane MacSoreley, who will be speaking about her yearlong investigation into Nicholas Rossi, a US fugitive who faked his own death and was found alive in Glasgow.
CrimeCon Glasgow, in partnership with CBS Reality, takes place on Saturday 16 September at Hilton Glasgow on William Street.
