A few weeks before Ed Kemper murdered his mother in April 1973, Santa Cruz Sheriff’s Sergeant Michael Aluffi was instructed to confiscate a gun illegally in the possession of an Aptos man. His name was Edmund Emil Kemper III and the address was 609A Ord Drive.

The instructions had resulted from a routine bulletin from the California Department of Criminal Investigation and Identification, which said that Kemper had purchased a .44 magnum revolver in Watsonville and falsely sworn that he had never been in prison.

The notice did not give any details of Kemper’s first two murders [of his paternal grandparents], listing only court disposition of the case and his prison record.

Aluffi drove to the apartment, but found no one at home. As he was walking away from the apartment door, a yellow Ford pulled into the parking space beside his unmarked vehicle. A large, brown-haired young man and a small young blonde girl were in it. It was Kemper and his fiance.

Kemper discussed the event in his 1984 interview for the documentary “Murder – No Apparent Motive”:

Journalist: Some police department actually came to your house to pick up a handgun. 

Kemper: The sheriff’s representatives, one of the detectives was upset because he heard I had a .44 magnum pistol and was a convicted mental patient and killed. He came to take the gun away. They were staking out the wrong house across the street and I’m playing around with a car, standing next to the gun in the trunk. They come over and asked, “Excuse me, sir. Do you know who lives in this house across the street?” Well, that house was 609 Harriet. He crossed back over to this side, 609 Ord, and they were looking for me and didn’t even know that was me. Bad news. Well, at any rate, we walk in the house and have them ask my mother about this other house, and I’m saying, “Hey, which 609 are you looking for?” They said, “Are you Ed Kemper?” “Yes,” and it goes on and I needed to find out what they were looking for, the murder weapon, the .22 automatic or the .44 magnum, and I don’t want to advertise that I’ve got a whole bunch of guns. So, I made a comment just to divide between the two and I suggest, “quite a little gun, isn’t it?”

He reported, “.44 magnum, I hope so.” Okay, because that loaded .22 was under the front seat and guarantee me an arrest right on the spot and the .44 was in the trunk. I forgot that. I took them in the house. We went into my bedroom and the closet doors open and I have a high-powered rifle with a scope on it with some other stuff in the house.

You had some other stuff in the house, yes?

Yeah, I had the personal effects of the last two coeds that had been murdered about two months before, right next to the guns in the closet in a box.

Could he have seen it?

No, but when he arrested me for having all those guns and went through the closet looking to see if there were any pistols or anything else, he wouldn’t have… couldn’t have helped notice a purse, a book bag and coed ID inside of those belonging to their two latest murder victims. I back up and I say, “Oh, excuse me. I just remembered something,” and instantly he responds to what I’m saying. My hand moves, back we go outside, and he’s still thinking, “Boy, this is a really nice and helpful guy here.”
