A Florida man is facing criminal charges for allegedly threatening to kill his college professor for scheduling an early morning final exam.

Rafael Decomas, 20, a student at Florida Atlantic University, reportedly threatened his data structure professor through Twitter over the scheduled 7 a.m. exam. According to WPLG, authorities managed to trace the tweet back to Decomas because the Twitter account was linked to the university’s Caribbean Student Association.

“Bey I gern f**king kill dis professor bey this is my confession to a premeditated murder,” he allegedly wrote early Tuesday.

The Miami Herald reported that the 20-year-old admitted to writing the tweet because he was “upset” about the exam’s start time, as it meant he would have to wake up at 5 a.m. to start his commute to the college.

“Decomas stated he did not intend to harm anyone and tweeted the post out of frustration,” the arrest report stated. “Decomas advised that he deleted the post soon after publishing it.”

The Florida Atlantic University student was arrested last week and charged with sending a written threat to kill or kill or do bodily injury. He was reportedly released from Palm Beach County jail after posting a $5,000 bond.
