I saw it too:

In 2014, Esteban Manzanares, 32, a Border Patrol Agent from Mission, TX kidnapped and raped a mother, her 14-year-old daughter, and a second teen who had crossed the border. He slit the mother's wrists, tried to break the daughter's neck, and left them for dead. He shot himself when police arrived.

I was there. They were indiscriminately firing multiple canisters into a huge peaceful crowd. Fucking cowards
