Discretion is advised.

This is 10-minute murder.

When Robert Durst was a young child, his mother climbed to the roof of their family home

and jumped to her death. Years later, Robert would claim that he had seen the entire thing,

which his younger brother, Douglas, denied, was true. It wasn't out of the ordinary for the two

brothers to disagree. During their childhood, they were

even sent to a counselor in an attempt to help the boys work through their extreme sibling

rivalry. The Durst children had been born into a real estate empire, but it didn't matter to

Robert. He spent his entire childhood and teenage years as a loner,

getting into fights, and alienating himself from his family. In 1971, Robert started dating

a woman named Kathleen McCormick. He was smitten, and the relationship moved quickly. After only a

handful of dates, he asked Kathleen to move in with him,

which she agreed to. They got married in 1973 and lived an uneventful life together, until

Kathleen vanished. In early 1982, Kathleen was just a few months away from finishing her degree

and becoming a pediatrician.

She was last seen at a dinner party with friends, where multiple people noticed her strange

behavior.

Kathleen showed up at the party out of the blue, dressed extremely casually in a pair of

sweatpants, and then excused herself after she received a phone call from Robert.

She had plans to meet a friend at a pub in Manhattan, but never arrived. Her friend was

concerned enough to call the police several times, but Robert didn't seem to share those concerns.

He only reported Kathleen missing after she had been gone for several days.
