April 3, 2012: Authorities said that a 43-year-old former student named One L. Goh walked into Oikos University and began a shooting rampage that left seven people dead and three wounded, trapping some in the building and forcing others to flee for their lives.

It was an "extremely chaotic scene," police Chief Howard Jordan said of the deadliest campus shooting in five years.

The chief said Tuesday that Goh killed his seven victims execution-style.

The shooter allegedly walked into the University's single-story building, took a receptionist hostage and went looking for a particular female administrator.

One witness said Goh told students: "Get in line and I'm going to kill you all." Goh walked into a classroom, lined up students against a wall and shot them one by one, Jordan said.

"This was a calculated, cold-blooded execution in the classroom," he said.

Goh ended his rampage by driving off in a victim's car, police said. The gunman allegedly drove about three miles from campus before surrendering to officers inside a supermarket.

March 31, 2014: Campus police at Georgia's Columbus State University fatally shot 20-year-old Zikarious Jaquan Flint after officers responded to a report of someone seen loading a gun, authorities said.

Flint wasn't a student at the university located 100 miles southwest of Atlanta near the Alabama state line, and no one else was hurt in the incident.

University Police Chief Rus Drew said officers were called at 2:35 p.m. Sunday and arrived three minutes later to an area near some campus apartments and began chasing a man on foot.

"There was a short foot chase and at some point the suspect turned and faced the officers and shots were fired," Drew said. He added that while there were some student witnesses, no lockdown was ordered because events had unfolded rapidly and authorities had determined that an "isolated threat" had ended.
