US Navy Hospitalman Casey Nutt, 26, was released from a trauma center Tuesday night, and Hospital Corpsman 1st Class Carlos Portugal, 36, remains in critical condition in the trauma center, according to a Wednesday press release from local and federal authorities.
According to the police, both victims were taken off the scene by helicopter.
The incident ended when the shooter was fatally shot by police after brandishing a weapon at the installations, Army Brig. Gene. Michael J. Talley said.
Authorities are investigating both the motive and circumstances surrounding the incident, Talley told reporters at a news conference Tuesday afternoon. Here’s what we know so far:
How the day unfolded
Frederick police chief Jason Lando said the first shooting took place in “a military facility” at Riverside Tech Park.
In a press release, police said the building is a warehouse rented by the Naval Medical Research Center, the Biological Defense Research Directorate, to store research supplies and equipment.
After the shooting, a victim entered a nearby business, Nicolock Paving Stones, and asked for help, one person there said.
“Our team was able to help them and called the authorities,” said Jeremy Mutschler, Nicolock’s director of marketing and advertising. The statement emphasizes that the shooting did not take place at Nicolock.
Officials identified that person as Nutt.
Portugal was found in the warehouse where the first shooting took place, the release said.
The gunner was stopped at the gates of the installation, but before the vehicle could be searched, the gunner left.
He was stopped about half a mile on the installation, where he got out of the car, brandished a gun, and was shot by police, Talley told reporters.
What a witness said
Garett Wagner, the operations manager at Nicolock Paving Stones, was talking about price changes with a new salesman when Nutt came running in, his military equipment covered in blood.
‘I was shot. Help me please. There’s an active shooter, he’s still after me, ”Wagner told him.
Wagner said he acted quickly and Nutt told him to get into the bathroom and close the door. The salesman and another employee locked the front door, he said.
“I can’t tell you if I was scared or scared or trying to help,” Wagner said. “I do not know.”
Wagner said he had all the workers gathered in the back and told them to close the door until he got back.
The manager called 911, but another employee had already called.
“You don’t think it’s going to happen here … then it happened, and it happened,” Wagner said. Did we do the right thing? Did we do the right thing? I guess so. I do not know.”
Frederick Police Chief Jason Lando said the shooter used a rifle but had not provided additional information about the weapon.
Frederick is located about a 50-mile drive northwest of Washington, DC. Woldesenbet had an E-4 rank and did not live at Fort Detrick, officials said.
Agencies that help the Frederick Police Department include the FBI; the Bureau of Alcohol, Tobacco, Firearms and Explosives; Maryland State Police; and the Frederick County Sheriff’s Office.
The FBI is handling the first shooting scene, officials said.
