(CNN) — three people were killed and at least one was wounded Friday in a shooting at the University of Alabama in Huntsville, a spokesman for the university said.
A female shooting suspect was in custody, said the spokesman, Ray Garner.
A spokeswoman for Huntsville Hospital said it had received three patients in critical condition from the shooting.
Trent Willis, chief of staff to Mayor Tommy Battle, said the incident occurred about 4:15 p.m. in Shelby Hall, which police were still searching.
“We do have some witnesses,” he said.
The 6-year-old, $60 million facility houses the Chemistry Department and is named for U.S. Sen. Richard Shelby of Alabama and his wife, Dr. Annette Shelby.
