A friend of Robert Durst's missing wife sat down with News 12 to discuss Durst's recent arrest in New Orleans.

Ellen Strauss, a good friend of Kathie Durst, says she has spent the last three decades wondering what happened to her. Katherine Durst was last seen on Jan. 31, 1982 at the age of 29. Her husband, Scarsdale real estate heir Robert Durst, told police that he dropped her off at the Katonah train station, less than 10 miles from their South Salem home.

Strauss claims that Robert Durst became violent toward his wife as she grew more independent of him by going to medical school. Strauss says that Kathie Durst would call her late at night to tell her about his violent fits.

Strauss took handwritten notes over the past 33 years in an effort to solve the mystery of Kathie Durst's disappearance. She says that she dug through Robert Durst's garbage, checked hospital beds in Boston and followed leads of reported amnesia victims, but nothing concrete ever came of it.

Robert Durst, 71, was arrested in New Orleans earlier this month on an extradition warrant from the Los Angeles Police Department. He is being charged with murder in the 2000 death of friend Susan Berman. Durst is also facing drug and weapons charges after a gun and marijuana were allegedly found in his hotel room.

Strauss says that Durst's latest arrest has her more determined than ever to learn what happened to Kathie Durst.

Robert Durst is scheduled to appear at an extradition hearing this Thursday. Strauss says that if he goes to trial, she will be in court every day until the jury decides his fate.
