Spooks Run Wild - 1941

Here is an East Side Kids movie with Bela Lugosi about the kids being at camp and hearing about a killer on the loose. At night they look around and one of them is shot by a grave robber, which forces them to take shelter in a foreboding mansion. PeeWee, the kid who was shot, acts very strangely while in the mansion, and the kids suspect it’s the creepy owner (Lugosi).
