The U.S. Navy Hospital Casey Nutt, 26, was released from a trauma center on Tuesday night and Carlos Portugal, 36, the hospital’s first class, remains in critical condition in the trauma center, according to a press release Wednesday from local and federal authorities.
Both victims were taken from the scene by helicopter, police said.
The incident ended when the gunman was fatally shot by police after swinging a weapon at the installations, Army Brig. Gen. Michael J. Talley said.
Authorities are investigating the motive and the circumstances surrounding the incident, Talley told reporters at a news conference Tuesday afternoon. This is what we know so far:
How the day unfolded
Frederick police chief Jason Lando said the first shooting took place at a military facility in Riverside Tech Park.
In a news release, the police department said the building is a warehouse rented by Naval Medical Research Center, directorate of biological defense research to store research supplies and equipment.
After the shooting, a victim entered a nearby business, Nicolock Paving Stones, and asked for help, a person there said.
“Our team was able to help them and called the authorities,” said a statement released by Jeremy Mutschler, director of marketing and advertising at Nicolock. The statement stressed that the shooting did not take place on Nicolock.
Officials identified that individual as Nutt.
Portugal was found in the warehouse where the initial shooting took place, the release said.
The gunman was stopped at the gates of the installation, but before the vehicle could be searched, the shooter took off.
He was stopped about 1 mile after the installation, where he got out of the car, swung a weapon and was shot by police, Talley told reporters.
What one witness said
Garett Wagner, the operations manager at Nicolock Paving Stones, spoke to a new salesman about price changes when Nutt ran in, his military fatigue full of blood.
“I was shot. Please help me. There is an active shooter, he is still chasing me,” Wagner said the man told him.
According to Wagner, he quickly took action and told Nutt to go into the bathroom and close the door. The salesman and another employee locked the front door, he said.
“I can not tell you if I was scared or scared or to help,” Wagner said. “I do not know.”
Wagner said he had all employees gathered at the back and said they should lock the door until he returned.
The manager called 911, but another employee had already called.
“You do not think it’s going to happen here … then it happened, and it happened,” Wagner said. “Did we do the right thing? Did we do well? I think so. I do not know.”
