(CBS/WTVR/AP) Investigators say 20-year-old student Justin Macklin whipped out a revolver and shot another man in the thumb during an argument on the campus of Middle Tennessee State University.
Police said Macklin has been charged with carrying a weapon on school grounds, aggravated assault and reckless endangerment. He was released on $18,500 bond from the Rutherford County jail, authorities said.
According to CBS affiliate WTVR, Macklin, from Memphis, got into an argument and shot at Austin Morrow of Murfreesboro, wounding the 20-year-old former student.
MTSU Police Chief Buddy Peaster said the two men had problems in the past but he did not say what prompted the shooting or elaborate on what they had argued about.
Police said the shooting occurred outside the student center, and the suspect then fled to a classroom building 200 yards away with Morrow in pursuit. At the building, police say, the suspect left a .32-caliber revolver, his shirt and two bags of marijuana. He was apprehended without incident when he left the building.
Morrow was treated on the campus by paramedics. First reports that the shooting happened in a classroom were incorrect, police said later Monday.
The campus of 24,660 about 30 miles southeast of Nashville was on alert for about 45 minutes.
Officials with Murfreesboro City Schools said nearby Bradley Academy and Discovery School at Reeves-Rogers were also placed on lockdown while police searched for the suspect. Restrictions have since been lifted.
Investigators have asked anyone who witnessed the shooting to come forward and speak with police.
Officials told the Associated Press that a court hearing is scheduled on March 2.
