Not enough information to tell if this was a raving lunatic, or just an OC'er out for an evening walk.
Campus advisory web page, will no doubt change soon, but for now:
Suspicious Person on Fredericksburg Campus
A student reported seeing an individual in possession of a handgun on campus walk near Simpson Library late Sunday evening. The individual was described as a white male with a black goatee and stocky build, about 5’5” tall, and wearing a dark hoodie shirt with red lining and blue jeans. He was carrying a backpack. Students and staff are being advised to shelter in place, be alert, and practice good situational awareness. The individual is being sought by campus police for further investigation. If you see an individual matching the description, please contact campus police and do not try to engage, stop or question him.

At least there are no issues with reposting content from a public university web page.
