The strange case of Robert Durst continues to get more bizarre by the day.
On March 14, Durst was arrested in connection with the 2001 death of his friend Susan Berman.
He has since been charged with first-degree murder, meaning that he could face the death penalty if convicted.
In the days following his arrest, those who knew Durst best - or simply encountered him during the decades-long period in which he somehow managed to avoid prosecution - have come forward with strange stories of the real estate heir's troubling behavior.
Earlier this week, Douglas Durst stated that he believes his brother killed seven pet dogs as "practice" before allegedly murdering his wife Kathleen McCormack in 1982.
Today, Durst has been accused of another disturbing act of animal mutilation by the former judge who presided over the 2003 trial in which Durst was acquitted of the murder of Morris Black.
In an interview with the New York Daily News, Susan Criss recalls making a horrific discovery outside of her home, three years after Durst's trial concluded.
"It was June 29, 2006," Criss tells the newspaper. "I came home from work around 5 pm, and you can imagine how hot it was. I saw something on the walk that leads straight to my front door.
"It was a little gray cat that had been cut behind the shoulders. It was a head with its two front legs...It was not just thrown there, it was placed there.
"I believe it was Robert Durst. I know this guy had a history of cutting up his dogs."
Criss says she first ran inside to make sure that Durst had not harmed her dogs. She then called local police, who performed several tests, but were unable to prove that Durst had killed the cat.
Criss says she believes Durst left the head as revenge for her testifying against him at his parole hearing.
Though he has yet to be convicted of a murder, Criss says that she believes "Robert Durst is a serial killer."
