Getreu's interrogation was presented last week during his trial in San Mateo County Superior Court for the strangulation murder of Janet Ann Taylor, who was found in a San Mateo County ditch on Sand Hill Road and Manzanita Way in 1974, just 13 months after Perlov's murder.
On Tuesday during closing arguments, Deputy District Attorney Josh Stauffer again reminded the jury of Getreu's inculpatory statements by presenting excerpts from the interrogation.
When Cortez asked if he was ever arrested, Getreu said no. Yet, Getreu, at age 18, had been arrested in 1963 for the murder of his classmate, Margaret Williams, and was convicted and sentenced to 10 years in a German prison. He also was convicted of statutory rape after accepting a plea deal in the 1975 rape of a Palo Alto teenager, Stauffer noted.
Getreu continued to lie about the Williams murder.
"Did you tell them you did it?" Cortez asked.
Getreu said no.
Getreu conceded he was arrested for raping Palo Alto teen "Diane Doe" after being confronted by Cortez.
"I was just accused, interviewed and that's it," Getreu said.
In fact, Getreu was arrested, convicted and pleaded guilty. He received a six-month sentence and was allowed to serve his jail time on weekends.
Doe testified at the trial that Getreu had strangled her and threatened to kill her if she made any noise while he raped her in her parents' home.
"I didn't serve any time that I know of. It was so piddly," he claimed.
Getreu also revealed that he knew more about the murders of Perlov and Taylor than someone without any involvement would know, Stauffer noted.
When shown a photograph of where Perlov had parked her car to gain access for a hike in the Stanford hills, Getreu said he "never went up in the hills. I've always been on this side, not the other side."
But how would he know what side of the open space area her body was found? Stauffer said.
Cortez showed Getreu a portrait photograph of Perlov and a crime scene photo of her face-down in the dirt, her skirt hiked above her naked hips.
"She's cute, anyway," Getreu said, chillingly.
"Did you ever fantasize about murder or raping girls?" Cortez asked.
"That's what it looks like," Getreu replied.
When asked if he would pass a lie detector test, Getreu replied, "It depends on what questions you ask me."
Getreu also began talking about a second murdered girl during the interview.
Cortez never brought up two girls, Stauffer noted.
Cortez was, in fact, only investigating Perlov's killing. Getreu admitted his knowledge of a second crime, Stauffer noted.
Looking at the photograph of Perlov lying face down, Getreu admitted some presence in the crime.
"OK, I had involvement, but I don't remember it," he said.
He tried to cover for mentioning a second girl by claiming that the portrait of Perlov he was shown looked like a different girl than the one of Perlov lying dead.
"It doesn't match. It doesn't even look like the same girl," he said.
He also tried to say the second girl he was referring to was Arliss Perry, a woman who was found stabbed to death in Stanford's Memorial Church in 1974. (Getreu is not connected to that crime. The main suspect died by suicide shortly before his arrest in 2019.)
Cortez noted that Getreu had taken responsibility for the murder of Williams in Germany and the rape of Diane Doe in Palo Alto, but why was he not taking responsibility for these other crimes?
"You had to have known this was coming," Cortez said.
"Yeah, I knew that," Getreu said, but he didn't understand "why it took so damn long?"
Getreu also thought that detectives would never be able to show he had a past conviction for Margaret Williams' murder and rape in Germany.
The original situation that led to his arrest wasn't true and he wasn't there, he said, not realizing that police had received all of the case files from Germany — and a confession he made to German authorities.
"What do you think your chances are ... that your DNA is there?" Cortez asked, referring to the Williams murder.
"There's a brick wall. You found out, but you couldn't find out," he said.
