A San Antonio man was arrested and charged with making a terroristic threat to the public after he threatened to kill NFL players, fans, and then himself during Sunday's game between the Pittsburgh Steelers and the Jacksonville Jaguars, according to Max Massey of KSAT 12, citing an arrest affidavit.

According to the affidavit, KDKA-TV in Pittsburgh received a threat from Yuttana Choochongkol, 30, on Thursday that outlined his plan to commit a mass murder during the game.

This Sunday's playoff game in Pittsburgh is going to be like no other. Why? Because it's going to be my last day on this pathetic planet. So why not take some innocent lives with me? The Steelers game will be packed, and that's when I plan on killing Steelers football players and fans before taking my own pitiful life. After all, what does a person that is going to commit suicide have to lose? Absolutely nothing. So why not take out some million dollar Steelers players before me? Sounds like a good idea. Hahahahahah

Choochongkol also sent a threat that was received by the director of security at Heinz Field. The threat was uploaded to heinzfield.com while the IP address and username was sent to the FBI. It was then traced to Worldwide Clinical Trials in San Antonio, according to the affidavit. Choochongkol has been a medical trial subject with the company a total of 25 times since 2011, per Massey.
