With a gun pulled, Anthony Miranda demanded money from the unnamed victim. He handed it over, but Miranda ordered him out of the car. The victim wrestled with Miranda, causing Miranda to shoot his own ankle, and then pinned Miranda down until police arrived.
And here's why this is being written up in a mixed martial arts blog. From the Chicago Sun-Times:
The victim, who told police he's a martial arts expert and ultimate fighting champion was able to pin Miranda down until police arrived. Police arrived to find Miranda with a face full of cuts and two black eyes. He was taken to Holy Cross Hospital for treatment, police said.
Judging by Miranda's face, the victim knew how to throw a punch or 20. It's understandable that the police didn't release the name of the victim. It's good practice to protect a victim's privacy.
No, the question is who describes himself as an "ultimate fighting champion," unless he is actually carrying around a belt? Though several UFC fighters call Chicago home, none are champions. What's more likely is that when describing his training, the victim had to invoke the name of the UFC, and this is what the police heard.
