BALTIMORE — Authorities say a man who was shot in the student center on the campus of Morgan State University on Wednesday is in critical but stable condition at Johns Hopkins Hospital.

The unidentified man, who is not a Morgan State student, was shot about 4:50 p.m. Wednesday on the northeast Baltimore campus. Authorities said late Wednesday the gunman, who also apparently wasn’t a student, was still at large.

Morgan spokesman Clint Coleman told The Associated Press the shooting was “not random,” adding that the victim and suspect likely knew each other.

“We believe the young man was targeted by the shooter,” Coleman said.

Witnesses “heard a verbal exchange between the two, which (indicated) they knew each other and this was about something that had apparently occurred earlier,” Coleman said Wednesday night.

He said one shot was fired. He said he did not know what the argument was about or what the two were doing on campus.

The campus was briefly on lockdown. An alert posted on Morgan State’s website at 6:11 p.m. called an all clear, although evening classes were canceled. A police tactical team searched the student center and did not find the gunman.

Baltimore city and campus police are investigating. Officers intend to sweep every building on campus overnight, Coleman said.

He said classes will resume Thursday morning.
