"I'm trying not to fall pray to hate, at the person who killed you, at the gringos, at Trump, at the terrorists ... because then I would be part of the vicious circle of judge and jury. They killed you out of hate for the freedom to be who you are and it makes me hurt inside because if there was anyone who always had a smile, who helped me, who was caring with me, my music and my madnesses, it was you.
