The Heimlich Death Maneuver is the title of a book found on one of the bookshelves in Wolf Heimlich's office. Laura chooses not to read far beyond the title after recalling some details she heard about the maneuver.
Supposedly, a practitioner of the Heimlich Death Maneuver wraps his arms around his victim's rib cage from behind, and squeezes until the victim's heart pops out their mouth. While Wolf Heimlich occasionally mentions the maneuver as a possible punishment for captured criminals, it is not known if he or anyone else has actually performed it.
