According to the sources, three men illegally entered the U.S. and crossed the Colorado River when they were detected. An lone Border Patrol agent responded and one of the three men attacked the agent. The alien grabbed for the agents service weapon. In the process of the agent protecting his service weapon, the alien grabbed his radio and began beating the agent about the head. The alien also grabbed the agents baton and used that to beat the agent as well.
The Border Patrol agent was left with head injuries and a severe laceration above his right eyebrow that required multiple stitches. The agents hands were also swollen after the life-threatening attack from the alien. The agent responded with deadly force and the alien attacker is now dead.
