Bryan Kohberger's defense team brought up the possibility that there were "alternate perpetrators" involved in the quadruple murders during a hearing in early May, but Kohberger is hardly the first person to point the blame at other individuals.
During a May 15 pretrial hearing, Judge Steven Hippler revealed that Kohberger's defense team made a filing that suggested an alternate suspect. Kohberger is charged with first-degree murder in the Nov. 13, 2022, deaths of University of Idaho students Xana Kernodle, 20, Kaylee Goncalves, 21, Madison Mogen, 21, and Ethan Chapin, 20.
While Hippler did not rule on whether he was going to allow Kohberger's defense team to present the "alternate perpetrators" theory during trial, he did ask for more evidence supporting their claim.
Former federal prosecutor James Trusty told Fox News Digital the strategy isn't necessarily a "full-throated defense" but rather a strategy used to create reasonable doubt within the jury.
Bryan Kohberger Defense Claims 'Alternate Perpetrators' In Idaho Student Murders
"The problem is, a lot of times, it's really designed to be not a full-throated defense to say Mr. Smith was the one that committed the murder, but just to create reasonable doubt. It's keeping in mind that the standard is tilted in favor of the defendant appropriately. And so the idea is to not always go full-throated and say he absolutely did it, but to make a run at it, to play it out in front of the jury, let them kind of come to their own conclusion that there's at least some doubt as to who did it," Trusty said.

Here's a look at other criminal cases in which the suspects invoked an alternate perpetrator.
O.J. Simpson was accused of killing his ex-wife, Nicole Brown Simpson, along with her friend, Ronald Goldman, on June 12, 1994.
Simpson's defense team attempted to bring in the alternate perpetrators' theory when they suggested in 1995 that the murders were done by Colombian drug lords, according to the New York Times.
Simpson's lawyer, Johnnie L. Cochran Jr., said in court that Brown Simpson and Goldman weren't the intended targets of the murder, but he suggested that one of her friends, Faye Resnick, was the person that Colombian drug lords had planned to kill.

Cochran said the drug dealers wanted to kill Resnick over money she allegedly owed.
Simpson was ultimately acquitted but said after the trial that he would keep working to find the person who killed his ex-wife and Goldman.
"My first obligation is to my young children, who will be raised the way that Nicole and I had always planned. … But when things have settled a bit, I will pursue as my primary goal in life the killer or killers who slaughtered Nicole and Mr. Goldman. They are out there somewhere. Whatever it takes to identify them and bring them in, I will provide somehow," Simpson said.

Peterson was found guilty and sentenced to life in prison without the possibility of parole.
