A candlelight vigil will be held Thursday night under the south stands of Ohio Stadium following this week's shooting in a campus building that left two university employees dead and another wounded.
The vigil was scheduled for 5:15 p.m., 10TV's Kevin Landers reported.
As the shooting victims are remembered, authorities continued to try and learn more about Nathaniel Brown, the disgruntled custodial employee who walked into the OSU maintenance building early Tuesday morning and opened fire.
On Wednesday, authorities shifted the focus of their investigation to Brown's home in north Columbus. Investigators were seen leaving the Grasmere Avenue home with boxes of evidence.
"Something like this is very tragic," University Police Lt. Rick Green said. "There had to be something that precipitated this and we're going to try and find out."
According to investigators, Brown walked into the maintenance building at about 3:30 a.m. and started shooting in an office. After killing supervisor Larry Wallington, 48, and wounding Henry Butler, 60, Brown turned the gun on himself.
Police speculated earlier this week that the shooting was job-related.
Brown had recently been given an unsatisfactory job performance and learned last week that he was going to be fired, 10TV News reported.
Ohio State administrators said they would review the school's hiring and employee review policies in light of the shooting.
Records obtained by 10TV News showed that Brown served five years in prison during the 1970s and 1980s for receiving stolen property, and a former co-worker said Brown was fired from a job at a car dealership for threatening other employees.
Ohio State knew nothing about those parts of Brown's history. The university hired a company to conduct a background check on Brown, but no details turned up, Landers reported.
In addition, Brown's employment application showed that he lied about having a felony record.
Ohio State president Gordon Gee said Wednesday that the university would take a look at the hiring process to see if anything needed changed.
"What we've done has generally worked very well," Gee said. "What we now have learned is the fact that there are some things that we need to look at, and that's precisely the things we'll take a look at."
Gee also spoke of Wallington's death, calling it a "tremendous loss for the university."
"I want Mrs. Wallington to understand that this is not just simply her family or the immediate people he worked (with)," Gee said. "It's a loss for all of us."
