Philadelphia Inquirer | Submitted by: Erick "Stelzenmuller, 49, lay dead in a corner of the attic near a cutup scuba suit and a mask with two tubes protruding from it... His obituary described him as the head of Penn Avionics, a firm that repairs electronics on private planes; it listed the dominatrix as "close companion"... "Looking at the scene, looking at her history, we are leaning toward some kind of autoerotic deal. It doesn't make sense to be geared up in scuba gear in the corner of an attic."
