According to LSU Police Capt. Cory Lalonde, police traced the 911 call about a bomb threat to a cellphone that could only make emergency calls. Officials then pinpointed the cell phone's location and searched homes in the Baton Rouge neighborhood before identifying William Bouvay Jr. as a suspect.
"Upon questioning, he admitted to making the phone call," Lalonde said.
The 42-year-old suspect is not connected to threats made against other college campuses in Texas, North Dakota, and Ohio last week, according to officials.
Bouvay is not a student and has no apparent connection to the school.
While there is no word on the motive, Bouvay will be charged with communicating false information of a planned bombing.
