Erotomania, Triangulation, and Homicide
A case of homicide by a 29-year-old male with erotomanic delusional disorder and various personality disorders is reported. Following a month of pursuit of a female stranger with whom he had briefly conversed in a local bar, he assaulted an automotive plant where she worked, delusionally believing that she was at imminent risk and needed to be rescued. One plant manager was killed and two police officers were wounded. The case illustrates the phenomenon of triangulation, where rage toward the rejecting object is displaced onto a third party, which is then perceived as impeding access to the victim and may be at risk for violent assault.
