Recently, various blogs have reported that Édgar Valdez Villarreal is the grandson of Rodolfo "El Gitano" Valdés Osuna, a notorious Sinaloa hitman from the 1940's who was part of a bloody campaign waged against peasant land reform. He later went on to work for drug lord Pedro Avilés Pérez, the founder of what would become the Cártel de Sinaloa.
It's been reported that El Gitano's two sons, La Barbie's father and uncle, were or are deeply involved in the business, possibly with the BL's.
