Cory Aaron Nowalk, 17, of Frederick, was located by police at his home on Wednesday after a warrant was issued for his arrest on charges of being an accessory to a first-degree assault and with illegally transporting a handgun, police said.
Police say detectives investigating the shooting determined Nowalk helped Dylan Gray, 17, also of Frederick, hide the handgun used in the shooting in the days following it. Nowalk admitted his involvement and led detectives to the gun, which another person allegedly was involved in hiding as well, police said.
Gray was arrested shortly after the shooting on his street, which police said occurred following an argument between Gray and a 16-year-old male acquaintance. Gray allegedly shot the boy in the chest, according to police, and has been charged with first-degree assault, reckless endangerment and two gun charges.
