The director of a shocking new Netflix documentary series has revealed why a woman who catfished her own daughter for years agreed to appear in the show.

Kendra Licardi, 44, from Michigan, served more than a year behind bars after she pleaded guilty to two counts of stalking a minor.

She had sent her daughter, Lauryn, and the girl's then-boyfriend, Owen McKenny, who were both 13 at the time, 'hundreds of thousands' of abusive and aggressive messages.

Yet when director Skye Borgman set out to create the Netflix series Unknown Number: The High School Catfish, Licardi was willing to share her side of the story.

'It was a long process with Kendra,' Borgman previously told Tudum, Netflix's blog.
