On Wednesday, US officials detained a 21-year-old self-professed member of the sexist "incel" movement who was accused of preparing a mass shooting at an Ohio university aimed at female students.

Tres Genco, who has self-identified as a member of the "incel," or involuntarily celibate subculture, was detained with illegal firearms in March 2020 after posting several posts on an incel website expressing hatred toward women, according to a statement from the Justice Department.

According to the accusation, Genco allegedly wrote a manifesto in which he stated that he would "slaughter" women "out of hatred, jealousy, and revenge."

Genco looked up sororities and a university in Ohio on the day he composed the manifesto, according to the probe. According to the statement, he also conducted surveillance at an Ohio university.

Genco stated in another note found by law police that he planned to "aim big" and kill 3,000 people, according to the statement.

He allegedly purchased tactical gloves, a bulletproof vest, a hoodie with the phrase "revenge" printed on it, a bowie knife, a skull facemask, and ammunition in 2019. In 2019, he spent three months in Georgia doing army basic training.

A court in Ohio condemned Genco to 17 months in jail last year for "terrorist threats."

He was released in January and was apprehended again on Wednesday by federal agents. He was discovered to be in possession of a firearm with a rapid-fire capability.

According to the statement, Genco was charged with attempting to commit a hate crime and illegally possessing a machine gun by a federal grand jury. Genco could face life in jail for the hate crime allegation due to his alleged intent to kill.
