On June 10, 1912, the Moore family and two visiting friends were found brutally murdered in the Moore house in Villisca, Iowa. All six family members and two guests (two young girls) had been bludgeoned to death with an axe. No suspect was definitively charged, though authorities considered local enemies, a transient minister, and other drifters. The crime scene was compromised early due to local curiosity-seekers roaming through the house.

A series of racially motivated attacks and murders occurred in the San Francisco Bay Area over about six months, resulting in at least 15 confirmed killings. The perpetrators, linked to a radical faction of the Nation of Islam (though disputed by mainstream NOI), targeted white victims at random. The codename “Zebra” came from the special police radio channel assigned to the case. Four men were eventually convicted, though speculation lingers about additional participants.

Between 2005 and 2009, the bodies of eight women were discovered in or around canals and backroads in Jefferson Davis Parish, Louisiana. All victims had similar backgrounds, often involved in sex work or had issues with substance abuse. Initially believed to be the work of a serial killer, subsequent investigations suggested potential police corruption or ties to drug trafficking. Many locals suspect a cover-up.
