Juan Julio Guerrero, an 18-year-old from San Angelo, Texas, was killed on March 26, 2016. He was found in the backyard of a home on East 22nd Street with a gunshot wound near his right eye and was pronounced dead at the scene. The shooting was part of a larger gang-related incident that also wounded 16-year-old Zane Lopez, who died of his injuries five days later.

Investigators linked the attack to threatening social media and text exchanges between Lopez and members of a criminal street gang on the day of the shooting. Subsequent arrests and prosecutions named several people in connection with the case. Gabriel Garcia, tried as a juvenile, was convicted of capital murder after being accused of sending menacing texts and providing the firearm used in the shooting. Nicholas Abel Rodriguez pleaded guilty to aggravated assault with a deadly weapon and received eight years of deferred adjudication with restitution and community service. Other individuals charged included Eric Ramos, Giliberto Salvador Reyes, Fred Angel Garcia, and Neo Kristofer Perez.

Anyone who knew Juan Guerrero, Zane Lopez, or who has information about the events on East 22nd Street on March 26, 2016, is asked to come forward.
