A deluded guy killed his girlfriend and her daughter because he thought they were witches casting spells onto him:

The district attorney, Richard A. Brown, said Mr. Amarillo told a 911 operator: “Two females are dead, they were assassinated, hurry they are dead. I killed them because they are witches. I want the police to kill me. I killed them with a hammer.”

Prosecutors said Mr. Amarillo, who was in a relationship with Estrella Castaneda, was seen walking to the street, clutching a Bible and saying: “I killed them. I killed them.”

An official familiar with the case said detectives were investigating whether drugs might have been involved. In statements to the police, Mr. Amarillo said he believed both victims had been “performing voodoo and casting spells” on him.
