(Reuters) – A North Carolina man died and 20 people were hospitalized due to apparent drug overdoses during a pop and dance music festival in Maryland, authorities said on Saturday.

Tyler Fox Viscardi, 20, of Raleigh, North Carolina, died after being taken to the hospital at 9 p.m. local time Friday after he attended an all-day Mad Decent Block Party festival in Columbia, about 20 miles (32 km) southwest of Baltimore, the Howard County Police Department said in a statement.

Authorities said Viscardi died of an apparent drug overdose, and investigators are working to determine what type of drugs were in his system.

A 17-year-old Virginia man, who attended the same event, was in critical condition suffering from what appears to be a drug overdose, according to the department.

Another 19 concert-goers were taken to the hospital during the event, also suffering from what authorities believe are drug overdoses.

The Mad Decent Block Party travels throughout the United States. Investigators said similar circumstances have unfolded at other Mad Decent Block Party events.

“We were shocked and saddened. … Our hearts go out to everyone impacted,” organizers said in a statement on the event’s website.
