- The two people who died were in some sort of relationship, official says
- Police are not giving out information about the identities of shooter, victim
- It was an isolated incident, police spokesman says
"From every indication that we have seen so far it appears to be a very isolated incident. It does have the appearance of being a murder-suicide," said Thom Berry of South Carolina's State Law Enforcement Division.
The two people involved had a relationship, but investigators are still trying to determine in what context.
Berry said the shooting occurred in a lab in the School of Public Health building and the shooter and victim were the only two people in the room.
Authorities weren't disclosing any information about the people who died in the early afternoon incident.
The university sent an all clear alert to students by 2:30 p.m., saying the building had been secured.
The building where the shooting occurred is in downtown Columbia, not far from the State House and some major businesses, CNN affiliate WIS reported
. The State House didn't go into lockdown, but people were warned to stay inside.
