The man suspected of shooting at the NSA building in Fort Meade, Maryland, and four other locations allegedly told police he was hearing voices at the time.
According to the Ann Arundel County Police Department, Hong Young, 35, first fired a gun on Feb. 24 at a 61-year-old man who had stopped to get gas at a Costco in Hanover. He was injured in the shooting but expected to survive.
Then at around 2:50 a.m. on Monday, Young allegedly opened fire in a Walmart parking lot in Laurel, Maryland. Roughly two hours later in Columbia, police received reports of shots fired at a movie theater.
Video surveillance footage showed that the same Lincoln Town Car suspected to be involved in the other shootings around the same time the shots were reported. There were employees inside the theater at the time, but no one was hurt when bullets pierced the front glass, according to Ann Arundel County police.
From there, Young drove to an overpass at the Inter County Connector in Prince George's County and allegedly opened fire, striking a tree service truck that was occupied by two people, police said. No one was injured in that incident either.
The next day on Tuesday, Young allegedly fired a gun near the National Security Agency in Fort Meade, striking the building at about 6 p.m.
Early Wednesday morning, the FBI issued a statement to BuzzFeed News saying it had a suspect in custody who authorities believed had fired a gun at various targets "around the Baltimore-Washington metro area in the last two weeks."
Young allegedly told officers that he was hearing voices at the time that told him to shoot at a random driver on Feb. 24, during which the 61-year-old man was injured.
Young was charged with attempted murder and assault in connection with that incident, the Associated Press reported Thursday.
