Man allegedly fatally shot by security guard at club in San Antonio

A San Antonio nightclub called it an act of defense and security, but the family of Alfredo Mireles calls it murder.

Now a lawsuit has been filed against Club Essence and DFW security.

The lawsuit says Mireles was in the nightclub back in January with his friends.

That's when a private security officer grabbed one of the men and pulled him outside.

Investigators say Mireles got involved and allegedly put the security guard in a chokehold.

That security guard then shot Mireles in the stomach, according to the lawsuit. He later died.
