The journalist Roberta Garza, author of the book Márcame, Amo, talks about Mexico's key role in the development of the Nxivm company.

Garza, whose book talks about Keith Raniere and the sexual sect within Nxivm denounced by several women, assures that Mexico was Raniere's "goose that laid the golden eggs."

The businessman was sentenced to 120 years in prison on Tuesday after being found guilty of extortion, sex trafficking, sexual exploitation of minors and human trafficking.

In his intervention in court, Raniere pleaded not guilty to the charges.
