Sheriff’s Homicide Detective
Pacifico worked nearly 200 murder and other suspicious death cases in the six years he was in homicide, and quickly became one of their lead instructors and public presenters.

Writers Homicide School
Pacifico was invited to speak to a group of fiction writers at a “Sisters in Crime” meeting in Pasadena, California. After this first writers group lecture, he was invited to several writing conferences and even at CBS Studios where he provided a two-hour keynote address on homicide investigations to a screenwriters group. Thus, “The Writers’ Homicide School” was born.

The Writers Homicide School has gained world-wide recognition receiving writers from as far away as Australia, Finland, Canada and Mexico, as well as writers from all across the United States who love hearing Pacifico tell them how real cops, conduct real investigations.
