MOBILE, Ala. – UPDATE 3:53 p.m.: Officials at Redstone Arsenal have determined that there was no active shooter or casualties involved in Tuesday’s incident at Redstone Arsenal, according to Col. Tom Holliday, the garrison commander at the facility.
At this time, the incident has moved on to the investigation phase, and an active shooter drill scheduled for later this week has been canceled. At this time, there is no evidence that any shots were fired, according to Holliday.
At about 9:40 a.m., base officials received two 911 calls about a possible active shooter at the Sparkman Complex, according to Holliday. Officers responded to the incident, and went through the process of securing the Sparkman Complex.
At about 12:50 p.m., officials determined it was an isolated incident, and resumed normal operations while continuing to clear the complex. At about 2:50 p.m., the building was determined to be clear, and the incident moved into the investigation phase.
“What I really want to make clear, is that when it comes to the safety and security of our workforce, our systems worked,” Holliday said in his press conference. “That was proven today. The drills and training that we do on a daily basis panned out and worked the way we needed it to work.”

Official spokesman Christopher Colster says the investigation on the base is ongoing. He says they do not think there is a threat at this point, and that is why they reopened the gates and lifted the lockdown for the base.
Colster says he’s still not sure what happened. “As soon as I know, you’ll know,” he said. He has no word that anyone has been taken into custody.
UPDATE 11:45 AM: CNN says the possible active shooter was reported at Building 5301, the aviation and missile command in the post’s Sparkman Center, according to spokeswoman Kim Hanson with the Army.
CNN also obtained an email sent to facility personnel and relatives that was more explicit, reportedly saying an active shooter was on the building’s second floor.
A possible active shooter forced Redstone Arsenal, a U.S. Army Post, to go into lockdown Tuesday morning.
According to a tweet from the base, there is a possible active shooter on the arsenal. Spokesman Christopher Colster spoke to media; he said Redstone Arsenal received reports of a person possibly armed with a weapon at a building on the base.
A reporter asked him what he would say to those with family members on the base; he replied they prepare for this situation all the time. He explained they coordinate with Huntsville police, the Redstone Arsenal’s own police, the FBI and more federal authorities. Colster said there were no confirmed casualties, and officials hoped workers could return to normal activities within a couple of hours.
A safety drill was planned for Wednesday, but Colster said the report of a shooter was not part of any exercise.
