Federal investigators said a man from Hillsboro has been arrested and charged with an attempted hate crime after allegedly plotting a mass shooting of women at a university in Ohio and having a machine gun.They said he was released after serving time for a conviction in Highland County and now, he is charged federally.Federal agents said the man wrote a manifesto saying he would slaughter women.They told WLWT they arrested him at a halfway house in Chillicothe on Wednesday.The feds said the case against Tres Genco, 21, from Hillsboro, started in 2019.They said Genco identifies as "Incel", part of an online community of mostly men who advocate violence against women believing they're unjustly denied sex or romance.A federal indictment showed between January and August 2019, Genco purchased tactical gloves, a bulletproof vest, a hoodie bearing the word "Revenge", cargo pants, a bowie knife and a skull face mask, as well as a rifle, two Glock 17 magazines, a 9mm Glock 17 clip and a holster clip.The document alleges Genco wrote a manifesto in August 2019 called, "A Hideous Symphony" and said he'd "slaughter" out of hatred, jealousy and revenge.Investigators found he researched sororities, referenced "OSU" and a huge kill count.Agents said Genco posted online he sprayed orange juice on women like a man named Elliot Rodger, a self-identified "Incel".Rodger, in 2014, killed six people and hurt 14 others outside of a University of California, Santa Barbara sorority house, federal officials said.They said from August 2019 to December 2019, he went to Army basic training in Georgia but was discharged for performance and conduct.By January 2020, agents found he drafted a document called, "Isolated", signing it as "your hopeful friend and murderer."They said he conducted surveillance on a university.Documents show in March 2020, Genco researched scanner codes for Columbus police and University police.A day later, Highland County deputies were called to his home where they said he locked himself in a bedroom with a gun but eventually gave up.ATF experts found the rifle and handgun he possessed worked as machine guns.Genco was convicted in Highland County Court in October 2020 for making terroristic threats.He was sentenced to 17 months in jail, but credited 224 days, according to online records.In January 2021, it appears he was given the "OK" for transitional control, out of jail.Highland County investigators said they called the FBI about the case, leading to these new charges.Genco is charged with attempting to commit a hate crime and illegally possessing a machine gun.Federal officials said the machine gun charge could mean up to 10 years in prison, while the hate crime charge could mean life in prison.Genco is now listed as booked in the Butler County Jail.
