David Avendaño Ballina

At the beginning of 2009, the possibility of the band's continued action was supposed, despite the affirmations of the federal government that the band was completely extinct.

On February 14, 2009, the corpses of two professional wrestlers were found inside a hotel in the Central district of Mexico City, the cause of death was defined as respiratory failure, traces of benzodiazepine were found in the bodies; a reason why it was immediately attributed to the Goteras.

On July 21 and August 12, 2009, María de los Ángeles Sánchez Rueda and Estela González Calva were arrested, the two sex workers who were responsible for the deaths of the two fighters. It was ruled out that they were members of "Las Goteras", it was determined that they were copycats. Both were sentenced to 47 years in prison.

On May 11, 2007, one of the most important cells in the gang was arrested in Mexico City; conformed by 18 people (11 men and 7 women). The detainees mentioned in their statements the existence of more cells and associated the band and referred to Avendaño as their leader. A year later, after several investigations, David Avendaño was arrested on February 12, 2008.

David Avendaño Ballina, alias "The Hamburger" (born in 1974) was the alleged leader of "Las Goteras", a gang of sex servants who poisoned and robbed their clients from 1997 to 2007, and who were responsible for dozens of deaths. He is linked to at least 70 murders (making him the third most prolific serial killer in Mexico). However, because of Ballina's motive, he is not typically classified as a serial killer.
