A Pennsylvania man embroiled in a fantasy football feud has fessed up to sending phony tips to law enforcement about a potential mass shooting and bombing plot in a bid to frame a rival member of his league. Matthew Gabriel, 25, of Philadelphia has pleaded guilty to two counts of interstate and foreign communication of threats stemming from two separate incidents, the first of which occurred in August 2023, the U.S. Justice Department announced Wednesday. Around that time, Gabriel got into a heated disagreement with an unidentified member of his fantasy football group chat, who planned to travel to Norway later the same month. Upon learning of his rival’s study abroad trip, prosecutors said Gabriel submitted an anonymous “tip” to the Norwegian Police Security Service — which investigates threats to the country’s national security — alleging the man was planning to carry out a mass shooting there. He wrote that his league mate would be “around Oslo and has a shooting planned with multiple people on his side involved. They plan to take as many as they can at a concert and then head to a department store,” according to the Justice Department press release. “I don’t know any more people then that, I just can’t have random people dying on my conscience,” the written tip continued. “he plans to arrive there unarmed spend a couple days normal and then execute the attack. please be ready.” It prompted a five-day investigation by law enforcement in Norway and the United States. Then, in March 2024,Gabriel, posing as someone else, sent warning of a potential bombing to the University of Iowa. In the email, with a subject line reading “Possible threat,” Gabriel also provided a screenshot from his fantasy football group chat. “Hello, I saw this in a group chat I’m in and just want to make sure everyone is safe and fine,” he wrote. “I don’t want anything bad to happen to any body. Thank you. A man named [PERSON 1] from I believe Nebraska sent this, and I want to make sure that it is a joke and no one will get hurt.” Prosecutors said the rest of the conversation, which was not provided in the screengrab, showed the comment was clearly made in jest. He faces a maximum possible sentence of five years in prison and a $250,000 fine. His sentencing is scheduled for Jan. 7.
