A deadly crime boss has escaped from prison when his brother came to visit and they exchanged clothes, allowing the latter to simply walk out of the front doors unchallenged with the visitor’s pass.

The prison break is believed to have included the full complicity of prison guards on duty and 18 staff members are reportedly under investigation.

Felipe N., alias ‘El Piruli’, a crime boss from the Mexican state of Puebla, is accused of killing three medical students and an Uber driver in February 2020.

Felipe, who was arrested on 24th November 2020, escaped from San Miguel prison in Puebla on 6th June.

According to the news site Excelsior, he walked out of the facility by simply changing places with his brother, name not disclosed, who has since been placed under arrest.

According to information from the State Attorney General’s Office (FGE), the killer’s brother entered the prison on the first day that visits were allowed due to the pandemic.

The pair reportedly swapped clothes, and Felipe left the prison with his brother’s visitor badge.

There have been no further updates on the local authorities’ attempts to track down the fugitive killer.
