Cops just love their pseudoscience bullshit, like Dave Grossman's Killology, it seems that they tout anything that lets them abuse, kill, and easily close cases without trying, just one of the many signs of how broken the criminal justice system is in this country, as well as others since the article also cites the use of Excited delirium by Belgian cops.

Then, Charles Wetli, then Deputy Chief Medical Examiner for Dade County in Miami, put forward an unusual theory. After examining the bodies of the deceased women, he concluded that they had all spontaneously dropped dead “due to a combination of cocaine and sex.” His bizarre prognosis continued: “Autopsies have conclusively shown that these women were not murdered” and “for some reason, with chronic cocaine use, the male of the species becomes psychotic and the female of the species dies in relation to sex.”

Wow. It's shocking how uneducated medical professionals can be even in the modern era.
