By the time authorities noticed that Tyrel Martin Marhanka had a sharp metal object in his hands, it was too late.
The 41-year-old American - who was sitting in a courtroom in Taiwan during his sentencing on drug possession charges - plunged the object deep into his neck, unleashing a gush of blood, according to the Taipei Times.
Some witnesses identified the object as a pair of scissors, but others said they saw Marhanka using two objects, both metallic. Court officials told the Times that the American separated a pair of scissors into two sharp blades.
The shocking act occurred moments after a judge gave Marhanka a four-year prison sentence for smuggling poppy seeds into the country and growing marijuana, according to the paper.
Marhanka was arrested in April 2015 after police discovered a large stash of illegal drugs at a rented house, which included hundreds of cannabis plants and 10 opium poppies, according to the Times.
