Morgan State University leaders on Robert BrownTuesday announced plans to build a wall around the campus following a shooting that injured five people, including four students, during homecoming week celebrations. Police, meanwhile, are calling on the public to help them identify two persons of interest in the case.

David Wilson, the president of Morgan State University, said during a campus town hall that the wall would effectively "eliminate unfettered access" by extending existing barriers by about 8,000 feet, encircling 90% of the campus.

“We’re doing this, let me be clear, not to keep out our neighbors and our community writ large," Wilson said. "We are doing it to keep out the bad actors."

In addition to the wall, other potential upgrades include installing more metal detectors in campus buildings, exploring weapons detection technology, increasing police patrols and building additional security guard booths.

Wilson said the anticipated total cost is more than $22 million and that a proposal will be sent to Maryland Gov. Wes Moore.

Baltimore police ask for help identifying two men

On Tuesday, the Baltimore Police Department posted images of two men sought in connection with the Oct. 3 shooting. The images, taken by surveillance cameras, were accompanied by a plea to the public for help identifying the two men. Days earlier, police released a video showing several people walking in a grassy area along with a request for tips that may lead to their identification.

The combined reward totals for tips leading to an arrest and charges is at $9,000, authorities said.

What happened at Morgan State University?

Gunfire erupted on campus around 9:25 p.m. following a dispute between two groups, authorities said. All the victims, between 18 and 22 years old, were unintended targets.

The shooting occurred just after a coronation ceremony, an event that was part of a pre-homecoming game ritual and prompted an hourslong lockdown on the campus as SWAT officers cleared a dorm building, where investigators believed potential shooters may have ran. None were found.

Each of the victims received non-life-threatening injuries and were hospitalized.

The incident canceled the rest of the week's homecoming events, including Saturday's football game, for the first time in the university's history.
