The shooting of five U.S. Army soldiers at a base in Georgia is the latest in a list of violent occurrences at American military installations over the years.

HOUSTON – The FBI said Tuesday that its investigation points to only one attacker in the shooting at a Texas naval air base, days after the agency suggested another person involved might be on the loose. FBI Supervisory Senior Resident Agent Leah Greeves said last week that investigators were working to determine whether a second person of interest was at large following the shooting at Naval Air Station Corpus Christi. Officials have identified the gunman as 20-year-old Adam Salim Alsahli, a Corpus Christi resident who had been a student at a local community college. Security officers shot and killed him after he opened fire while trying to drive a truck through a base entry gate. The FBI said Tuesday that Alsahli was a Syria-born American citizen.
