Excerpts from Stephanie Birkitt's private diary make up the centerpiece of Robert Halderman's alleged plan to extort $2 million from David Letterman.
Halderman (who is also known as Joe Halderman) threatened to expose his inter-office affairs if he did not comply, according to law enforcement officials.
The writings of Stephanie Birkitt was presumably not meant for the eyes of former lover Letterman, or a more recent one, CBS News producer Halderman.
But pages copied from her diary are critical to the police investigation.
Stephanie Birkitt, 34, was an assistant on The Late Show with David Letterman and frequently appeared on camera herself, along with the host, in comedy skits.
She was also once his lover, according to her own diary (another woman, Holly Hester, is alleged to have had an affair with Letterman while he was still at NBC).
Later, she became romantically involved with Robert Halderman. The couple lived together in his Norwalk, Conn., home until August, when they reportedly split.
Stephanie had once worked on 48 Hours Mystery, the show where Halderman was a well respected producer. CBS News has suspended him since his arrest.
Robert Halderman apparently copied pages from Birkitt's diary before they broke up, using them together with e-mails and other information in a package left in Letterman's limo that was intended to extort money from him.
Halderman's attorney, Gerald Shargel, said Monday that Letterman is a master manipulator and only telling one side of the story, while the charges against his client are "so obviously out of character to the point of not making any sense."
After he pleaded not guilty in a Manhattan court last week to a count of attempted first-degree grand larceny, Halderman is currently free on bail.

About a month ago, it occured to me that Stephanie was never on the DL show any more, neither was the "Hello Deli". Now I know why Stephanie isn't but I wonder what happened to the "Deli".

Well, now he won't have to worry about everyone thinking he is homo as he did on the show when he announced that his girl friend was expecting his baby and that he has had sex at least once. WHAT a women. Stays with him for years, has his kid, rides in a pickup in Montana to get married to him in a courthouse when the kid is five years old, then to have him screwing around with other women in between. Lady, get checked for disease, then send him home to mom! No amount of money is worth it.

Clare you moron, there is no proof he was with anyone after he met his wife.
And are you idiots blind? An ex-love has her privacy violated by one of her exes - that's the crime here. Not that Letterman had a bit of a fling years ago.
