The murder of Kathy Francis is considered the first confirmed killing committed by Herbert Mullin. The attack marked the beginning of a series of murders driven by delusional beliefs. Mullin believed his actions were preventing natural disasters, a theme that would continue throughout his crimes.
Mullin picked up Francis while she was hitchhiking and later killed her before disposing of her body. The attack appeared opportunistic.
At the time, the case was not immediately linked to a broader pattern.
