A Maryland man has now been linked to nine separate incidents in which gunshots were fired at random buildings and drivers around the area, authorities said Wednesday.
A day earlier, that number was seven, but Anne Arundel County Police now say they've connected the suspect, 35-year-old Hong Young, to shooting damage at a public library and the Maryland Live! Casino.
Police said the shooting at the Russett Library in Laurel happened about 3 a.m. March 2, shortly after they received calls about shots fired at a Walmart across the street. At the library, investigators found a bullet hole in one of the windows and in the ceiling.
Police say they've also linked Young to bullet holes found on the exterior of the Maryland Live! Casino.
Young is being held without bond on charges of attempted murder and assault in a Feb. 24 shooting that injured a 61-year-old man. The victim had stopped at a Costco at Arundel Mills to get gas. He was grazed by a bullet and his vehicle was struck several times.
Young was arrested March 3 following two more shooting incidents. That afternoon, a tree service truck with two men inside was hit by bullets on the Maryland Intercounty Connector (ICC). One man was injured by shattered glass; the other found a bullet fragment in his clothes but was not hurt.
Around 6 p.m., a building near the headquarters of the National Security Association (NSA) at Fort Meade was hit by bullets. No one was injured.

Young has no terror-related ties, a federal official told NBC Justice Correspondent Pete Williams. The suspect suffers from mental health issues, Williams reported.
From 2012 until his resignation in May 2014, Young had worked as a correctional officer at a Jessup facility, said Maryland Secretary of Public Safety Stephen Moyer. Nothing significant was found in his file, Moyer said.
In the wake of Young's arrest, investigators spent hours searching his Beltsville home, where they recovered 10 weapons, including a pistol, and hundreds of rounds of ammunition. Police said Young owned all the weapons legally.
