Tune in to “Robert Durst and My Quest for Justice,” with Judge Jeanine Pirro, Saturday and Sunday at 9p ET on Fox News Channel.

On "Fox and Friends" this morning, we got our first look at Judge Jeanine Pirro's one-hour special that focuses on her pursuit of justice for Kathleen McCormack Durst. 

In the upcoming special, “Robert Durst and My Quest for Justice,” Pirro and the Fox News team hit the ground to examine the 1982 disappearance of Durst's 29-year-old first wife. 

For more than 15 years, the former district attorney for Westchester County has worked tirelessly to crack the case. McCormack was a stunning fourth-year medical student when she suddenly went missing.

"I knew immediately in my gut, that once you put the pieces together, this guy was responsible for her disappearing. ... It was my mission. I was determined not to let wealth, power and a name interfere with justice," she recalled, criticizing the NYPD's investigation of the disappearance.

National interest in Durst, a wealthy real estate heir, and the suspected murders linked to him, spiked earlier this year during the HBO special, "The Jinx."

The show concluded with Durst seemingly admitting on a hot mic that he "killed them all," an apparent reference to his first wife and the 2000 death of friend Susan Berman in California. 

Durst also killed his elderly Texas neighbor, but he argued it was in self-defense and he was acquitted in 2001. He is currently in prison on a gun charge in Louisiana.

Hear what Judge Jeanine had to say in the video above, which includes a sneak peek at her trip to the Pine Barrens of New Jersey, where trackers searched for McCormack's body in 2002.

"I believe he killed her," said one of the trackers to Pirro.
