Police seized 26 guns and 67 containers of ammunition. And the state fire marshal's office is looking for suspects who attempted to burn down a sign in a portable toilet at Gambrill State Park in Frederick County. It occurred just before 1 a.m. on Monday when a fire was set near the sign in the portable toilet. The fire was discovered by a passerby. I'm Kevin McManus, WFMD News.
