An influencer murdered in the middle of live. This is the first case that Casos del Crimen con El Sargento, the new podcast that has been available on all digital platforms since Thursday, May 22, brings to the table. The initial episode deals with the shocking death of Valeria Márquez, the young Mexican woman who was shot while broadcasting live on TikTok. What seemed like just another viral crime is actually the tip of something much darker… and this podcast exposes it like never before.
Carlos Cornejo knows what is behind the crime scene. He was a police sergeant in the United States and today he puts his experience at the service of those who want to understand the real -and often silenced- side of violence. Casos del Crimen con El Sargento is produced by QuéOnnda and Nueva Network, and every Thursday comes with a new case told from the point of view of someone who was “on the other side of the yellow tape”. You can already listen to it on Spotify, Apple Podcasts and YouTube.
