Sounds like one of those cheap pocket-size pea shooters...someone may have dumped out the contents of the drawers after someone passed away and never even realized it was there.
Always question heavy socks and underwear...I think that was one of the top ten hiding places at one time...the sock/underwear drawer beside the bed.
SO had one of those little things...it was cheaply made and lacked safety features. Almost ended up in the washer once.
