One person was killed and another injured early Sunday in a shooting on the campus of Winston-Salem State University in North Carolina, the university's website said.
The names of the victims have not been released, and the alleged gunman is still at large, local media reported. Campus police and local police could not immediately be reached for comment.
The campus was initially placed on lockdown, but that was later at least partially lifted.
"The campus community is advised to exercise caution while on campus today, and stay away from the restricted areas on campus," the university said.
This North Carolina shooting comes one day after gun violence in downtown Colorado Springs left four dead. A suspect killed three people before dying in an exchange of gunfire with police, authorities said.
The killings and the suspect's shootout with police in front of a Wendy's restaurant unfolded about a mile from the U.S. Olympic Training Center in the central Colorado town.
Matt Abshire, 21, told the Colorado Springs Gazette on Saturday that he looked out from his apartment and saw a man with a rifle shoot another person.
Abshire then went outside and saw the shooter open fire and strike two women, one of whom appears to have been shot in the face, he told the newspaper.
Colorado Springs Police said they closed off several streets to investigate the shootings, which spanned at least five city blocks.
Police spokeswoman Lt. Catherine Buckley declined to release any details on the shooter or the ages or genders of the three victims.
Authorities said there appears to be no further threat to the Colorado Springs area, which is home to the U.S. Air Force Academy and has a population of about 445,000.
Just over three years ago a gunman killed 12 people at a movie theater in the Denver suburb of Aurora in an attack that ranks as one of the deadliest mass shootings in U.S. history.
