Kathie Durst Disappearance

Jan. 31, 1982
By early 1982, the couple were living in different apartments in Manhattan, but still shared a cottage in Westchester County, New York, according to a People magazine article about the search for Kathie.

Kathie's friend Gilberte Najamy had a party in Newtown, Conn., on the night of Jan. 31, but Kathie left after receiving an angry phone call from her estranged husband.

"She came to the house, she was visibly upset. Things were not going well that weekend. She made phone calls back and forth to Bob, Bob would call the house 'I want you home now.' She didn't want to go," Najamy told ABC News in 2001.

"The last conversation that I had with Kathie was a very powerful conversation and as she was leaving my house, she turned to me and said 'gilberta, promise me if something happens to me you'll check it out. I'm afraid of what Bobby might do,'" she told ABC.

Durst told investigators that they got into an argument that evening when she arrived back at their South Salem, New York cottage, but that he drove her to the train station and she headed back into Manhattan. Five days later, Durst contacted police to tell them Kathie was missing.

According to People, an employee at Kathie's building thought he saw her from behind the day after Durst said she returned to Manhattan, and the dean of the medical school where Kathie was studying said he received a call from a woman identifying herself as Kathie who said that she was sick and was going to be missing class.

The Murder of Susan Berman

2000
Westchester County investigators reopen their investigation into Kathie Durst's disappearance, which at that time was still ruled a missing persons case rather than a murder. The next year, Kathie was declared dead though her body was never found.

Investigators were scheduled to speak to Susan Berman, a good friend of Durst's who lived in California. But on Christmas Eve, just days before her scheduled meeting with investigators, Berman was found in her home, fatally shot in the back of her head.

According to a 2001 New York Times article, Berman's family and friends did not suspect Durst at the time and felt that he would never hurt Berman, who he was so close to that he gave her away at her wedding in 1984.

The Los Angeles Police Department said that Berman's death has been an open investigation ever since.

October 2001
Durst was arrested in Galveston, Texas, for the murder of Morris Black, his 71-year-old neighbor who was found dismembered.

Once police start looking into the murder, they discover that Durst had rented an apartment in Galveston in April, according to The New York Times. He had told the landlord that he was renting the home for his mute sister-in-law, and gave the name of one of his childhood classmates. Durst was seen dressed up as a woman at the library and at local restaurants.

Durst was charged with the killing of Black, but claimed that he did so in self defense. According to the Dallas Morning News, he became a fugitive after being indicted but was later found by authorities.

During the 2003 trial, the Associated Press reported that Durst admitted to using a paring knife, two saws and an ax while he was dismembering Black's body, which he later dumped in Galveston Bay. A jury later acquitted Durst.

Robert Durst Found Not Guilty of Murder

2004
The AP reported that Durst pleaded guilty to bond jumping and evidence tampering. He was released on parole in 2005. After that, however, he had another run-in with the law when he violated the terms of his parole by returning to the home where he killed Black, which resulted in him having to spend four more months in jail.

His case received renewed attention when a movie, titled "All Good Things," was released detailing a fictionalized version of Durst's life, with the Durst character being played by Ryan Gosling. Durst contacted the film's director after its release, and their ensuing interactions result in an HBO series.

Orleans Parish Sheriffs Office

Robert Durst was arrested in New Orleans, Saturday night, March 14, 2015.

March 15, 2015
Durst, 71, was arrested by FBI agents Saturday afternoon at a New Orleans hotel, a day before the final episode of the HBO series aired, a law enforcement source briefed on the investigation told ABC News.

FBI agents believed Durst may have wanted to flee the country, possibly to Cuba, as he registered under an alias at the hotel, paid with cash, and was found with fake documents, said the source. Saturday marked the first nonstop flight from New Orleans to Cuba since 1958.

"As a result of investigative leads and additional evidence that has come to light in the past year, investigators have identified Robert Durst as the person responsible for Ms. Berman's death," the Los Angeles Police Department said in a statement.

In the HBO series, Durst appeared to have admitted to the killings of Berman and his wife, and was heard on audio tape saying that he "killed them all, of course." The audio recording was captured on a microphone he was wearing while he was in the bathroom. The filmmakers said they didn't discover the audio years after it was recorded.

March 16, 2015
Durst appeared in court in New Orleans this morning and waived his right to fight extradition, meaning that he will appear in California to face charges though no date has been set. The Los Angeles DA charged him with one count of first-degree murder with the special circumstances of murder of a witness, as well as lying in wait and gun use allegations.

The charges, which carry the death penalty, are in connection with the 2000 murder of his friend, Susan Berman, in Los Angeles.

"Let me just say that we came here to waive jurisdiction and to go back to California and to get it on," Durst's lawyer Dick DeGuerin, who represented him in the 2003 case relating to Black's death.

"Bob Durst didn’t kill Susan Berman -- he’s ready to end all the rumor and speculation and have a trial but we’re frustrated because the local authorities are considering filing charges on him here and holding him here," DeGuerin said in front of court.

Louisiana State Trooper Melissa Matey confirmed to ABC News tonight that an arrest warrant was issued for Durst and he was rebooked in the Orleans Parish Jail under two new charges: convicted felon in possession of a firearm, and possession of a weapon with a controlled dangerous substance, which was a small amount of marijuana.
