Col. Thomas Holliday, Redstone Arsenal Garrison Commander, says there was no shooter or casualties after a reported active shooter situation at the Sparkman Center on post.
Redstone Arsenal received two 911 calls at 9:40 a.m. about a potential active shooter at the Sparkman Center complex. The calls came from a building on the complex. The initial reports of someone hearing shots fired and someone seeing a weapon were not credible reports.
Col. Holliday would not say whether or not investigators have interviewed the 911 callers at this time.
Redstone Arsenal sent a Facebook message at 10:24 a.m. alerting people of an active shooter situation.
The arsenal allowed most normal activities to resume just before 1:00 p.m., and the building was cleared just before 3:00 p.m.
"The drills and training we do on a daily basis panned out and worked the way we needed it to work," said Col. Holliday.
Local, state and federal law enforcement assisted in the response.
The Sparkman Center is a 1.5 million sq. ft. complex.
Redstone Arsenal is Madison County's largest employer. The arsenal is 38,000 acres, and it is home to the U.S. Army's missile and rocket programs. The NASA Marshall Space Flight Center is also located on post. The Department of Homeland Security and the Department of Justice also employ workers at Redstone.
The FBI has employees at Redstone Arsenal, and some work with the bureau's Terrorist Explosive Device Analytical Center (TEDAC). A spokesperson says more agents from the Birmingham field office are heading to the arsenal at this time.
Huntsville Mayor Tommy Battle issued a statement after there was no longer a threat.
“I am proud of Huntsville police officers, HEMSI, Fire & Rescue and our public safety network for their quick help in assisting our Redstone partners,” said Mayor Tommy Battle. “Our officers worked hand in hand with Team Redstone to secure facilities and monitor gates. Strong cooperation for a strong community.”
Redstone Arsenal has canceled a scheduled active shooter drill Wednesday.
"We believe we learned everything we needed to as a part of the event that occurred today," Col. Holliday said.
Holliday did say there were "a few" heat-related medical calls as a result of the emergency response.
The U.S. Army Criminal Investigation Command is investigating the incident. It is unknown if the calls were a hoax or not.
