Newsweek magazine reported that the FBI has asked the U.S. Department of Defense to provide information about Fort Bragg's sniper school, specifically about students who were rejected or flunked out.
Anna Taylor, Fort Bragg media relations officer, said officials at the army base are researching media inquiries about snipers and sniper schools but said she could not comment on government requests.
Capt. Kostal, commander of the U.S. Army Sniper School at Fort Benning, Ga., said law enforcement officials have not requested records of former students.
Kostal estimated that 50 percent of those accepted into the school flunk out each year but would not comment on the total number accepted annually.
But he said there is no concern about those who fail out because all candidates must take three psychological exams before enrolling.
Law enforcement officials investigating the latest sniper shooting are not seeking information assistance from the military, said Officer John Carney of the Fairfax County, Va., Police Department.
"(The department) is taking information from anyone but is not actively soliciting any military assistance," he said.
But Carney, who described the Fairfax County Police Department as "frantic," said local law enforcement agencies still are in control of the investigations because these are local crimes.
"We are not at a point where the federal agency has taken over," Carney said.
