A man accused in several Maryland shooting incidents in recent weeks, including one targeting a building on NSA grounds and another on the Intercounty Connector, has been linked to two more, authorities said Tuesday.

Laurel police said in a statement that Hong Young, 35, is believed to have fired four bullets into a window of the Grand E Buffet restaurant in the 9600 block of Fort Meade Road. Police said bullets from the storefront were sent to the Prince George’s County firearms unit for analysis.

While officers were at the Grande E. Buffet, Laurel police were called to the Teppanyaki Grill and Supreme Buffet in the 14100 block of Baltimore Avenue, where they found windows had been shattered. Video surveillance shows a man driving up to the restaurant in a grayish-blue Lincoln Town Car — one similar to a vehicle police say Young drove in other incidents.

The video showed the man getting out of the car and repeatedly throwing rocks at the restaurant before driving away.

Young is believed to have been involved in several other incidents in the region in recent weeks, authorities said.

Young, a former prison guard, was arrested last week and has been accused of firing shots along the Intercounty Connector in Prince George’s County, at a National Security Agency building at Fort Meade, and in at least three other incidents in Anne Arundel and Howard counties.

Authorities also said they are investigating whether he was involved in a shooting incident at the Maryland Live casino at Arundel Mills mall.

No one was seriously injured in the shooting incidents. Young has said that “he was hearing voices” that told him to fire his weapon, authorities have said.

Laurel police said they will be working with other jurisdictions to bring additional charges against Young in the two incidents that occurred within Laurel city limits.

In a search of Young’s Colonial-style brick home in Beltsville, Prince George’s police confiscated 10 firearms — handguns and long guns — hundreds of rounds of ammunition and a crossbow. Authorities said the weapons were legally obtained.
