A college student in Florida threatened to kill his professor for scheduling a final exam at 7 a.m., university police officials said.

Rafael Decomas, a 20-year-old student at Florida Atlantic University, was arrested Wednesday after sending a tweet at 1 a.m. Tuesday warning his data structure professor that his upcoming morning exam simply wouldn’t work with his schedule, WPLG reports.

“Bey I gern f—ing kill dis professor bey this is my confession to a premeditated murder,” Decomas tweeted from the Twitter handle @Ashelaniqua, according to an FAU police report obtained by the station.

Investigators were able to link the account to Decomas because it associated him with the Caribbean Student Association at the 26,000-student university in Boca Raton.

Decomas told police he was angry that he had to get up at 5 a.m. to leave his residence in Riviera Beach to make it to campus in time for the early exam. But he insisted he never intended to hurt anyone and merely sent the tweet “out of frustration,” according to the report.

“Decomas advised that he deleted the post soon after publishing it,” the report said.

Decomas’ Twitter account was no longer active as of Tuesday and a message seeking comment was not immediately returned.

The Miami Herald identified the professor involved as “Carl Weiss,” citing the campus arrest report. But the university’s faculty directory contains only a listing for “Karl Weiss,” an adjunct faculty member in the computer and electrical engineering and computer science departments.

A message seeking comment from Weiss was not immediately returned.

Decomas, who was charged with sending a written threat to kill or do bodily injury, has been released on $5,000 bond, WPLG reports.
