The “Marianist First” statement refers to the Marianist Hall dormitory that houses more than 380 students on the UD campus.
Just before noon, a second Yik Yak post came from the same person: “9 minutes I’ll strike,” the affidavit stated.
Yik Yak is a social media platform that allows users to anonymously create and view discussion threads within a 5-mile radius.
UD Public Safety officers responded around 11:10 a.m. to the area of Marianist Hall. Chief Kidd also requested assistance from the Dayton Police Department and Oakwood Public Safety Department and also contacted the FBI’s Dayton regional office, which was able to identify the person believed to have posted the threat as Hartrich, the document stated.
UD police arrested him about 12:35 p.m. inside his campus residence.
Hartrich initially denied posting the threat and said he lost his phone at 10:10 a.m. while attending class at the Science Center but that he later found it sometime after 10:50 a.m. on a bench outside the main entrance to Kennedy Union. However, after investigators asked him to review his story and his steps taken, “Hartrich confessed to posting the threat.”
He told investigators that he posted the threat as a joke, according to the affidavit.
He also allowed police to search his dorm room, but no weapons were found.
Hartrich is next scheduled to appear Nov. 17 in court.
