Officers responded to a report of a stabbing in the area of 119th Street and Assawoman Drive about 12:25 a.m. and found an 18-year-old woman, a 19-year-old man and a 20-year-old man all suffering from stab wounds, police said.
A description of the suspect's vehicle was obtained and shared among police agencies, and a Maryland State Trooper patrolling in the beach town soon stopped the car near 31st Street and Baltimore Avenue, police said.
Police took Trevor Lee Testerman, 18, of Thurmont, and a 17-year-old girl from Frederick into custody, police said.
Testerman has been charged with three counts of first-degree assault, three counts of second-degree assault and one count of reckless endangerment, police said. He is being held in police custody, awaiting an appearance before a city court commissioner.
The girl, who has not been identified, has been charged as a minor with accessory after the fact and referred to juvenile services.
The 19-year-old man wounded in the incident refused medical treatment. The 18-year-old woman and 20-year-old man were flown to Peninsula Regional Medical Center, where police said they were in "stable" condition.
None of the victims were identified, and further information on their conditions could not be determined.
