La Dama del Silencio. El caso Mataviejitas

God this one was a very chilling and very well documented documentary, this case was a big thing in the late 90s and early-late 2000s in Mexico. I was not mentally aware at the time when this woman commited her crimes cause I was still a kid, but now watching her story and all the terrifying and evil things she did, my god she was a terrible human being. I learned more about this case with this documentary, it has comments from some of the police department people that were working at the time, and family members of some of the victims of this woman. I am not a fan of documentaries but this one really gave me the chills, I highly recommend watching it.
