An illegal immigrant and member of the notorious MS-13 street gang was convicted Monday by a federal jury on several charges, including a violent 2017 attack on a man in Nashville, prosecutors said.

The U.S. Attorney’s Office said Gerson Serrano-Ramirez, 31, of El Salvador, was accused of inviting a person to his home after the man asked him to stop disruptive gang activity at a nightclub.

Once at the house, Serrano-Ramierz pointed an assault rifle at the man before strangling him with the rifle strap. He continued the assault by “spraying bleach into his eyes and then attempted to suffocate him by placing a plastic bag over his head,” prosecutors said.

The 31-year-old then clamped the man’s finger with a pair of pliers while holding the rifle on him, telling the man if he told anyone about the assault that he would kill him and his mother.

Serrano-Ramirez, who went by the street name Frijole, was indicted in August 2017 and convicted Monday on all counts after a 3-day jury trial. Authorities said the 31-year-old had previously been deported, and illegally re-entered the country before the assault.

Serrano-Ramirez faces a mandatory minimum sentence of at least 30 years and up to life in prison when he is sentenced in January 2019.
