Where did the men drown ?
The Smiley face murder theory ( variations include Smiley face murders , Smiley face killings , Smiley face gang , and others ) is a theory advanced by two retired New York City detectives , Kevin Gannon and Anthony Duarte , that a number of young men found dead in bodies of water across several states over the last decade did not accidentally drown , as concluded by law enforcement agencies , but were victims of a serial killer or killers .
