The gunman, identified as University of Georgia professor George Zinkhan, 57, drove off in his car and was being sought by authorities, the Atlanta Journal-Constitution reported on its website.
Two other people were wounded in the shooting, the newspaper reported.
The Georgia shooting was the latest in a spate of high-profile mass killings in the United States in recent months — including half a dozen rampages since March. The latest, on April 18 in Maryland, saw a man kill his wife and three small children before committing suicide.
Zinkhan's motives were unclear, but witnesses told the Journal-Constitution he argued with an unidentified man at the Athens Community Theater before he left and returned minutes later brandishing two handguns.
The people killed were identified by a theater company official as Marie Bruce, 47 — Zinkhan's wife — Ben Teague, 63, and Tom Tanner 40. Bruce and Tanner were officials in the theater company.
"We watched it happen," witness Beth Kozinsky told the paper. "We were all in shock." She said the theater company was hosting a homecoming lunch for current and former members at the time .
My question to christians is, why does even ONE christian do an act of evil when the holy spirit is guiding him/her?
