Porn Valley- Mark D’ull, owner of a porn company called Best Parts Video learned, despite what your parents told you, that dating the boss’ daughter is the quickest way up the ladder of success. And D’ull got a quick goose up the rungs last week when multi-zillionaire Kirk Kerkorian’s people came to pay him a visit at Best Parts.

D’ull has been dating Kerkorian’s daughter Tracey, and it came down to this: D’ull was given an offer he could hardly refuse – get out of the porn business and how much is it going to take to do that. D’ull, who owes money all over the place, didn’t think twice and is apparently being set up in the real estate business by pop.

Adultfyi first reported the D’ull-Kerkorian romance earlier this year when D’ull, in an apparent psychotic fit, went over to Dane Productions in March and began threatening people before they called the authorities on him. Here’s a repeat of that story:

Porn Valley- I was there as some of this story unfolded. I went to visit an adult company this afternoon and there were cops in the lobby. They’re looking at me. I’m looking at them. They’re taking statements from several people as I walked in the door. Is this a bust I’m wondering? A 2257 visit? Had Bridgette Kerkove dropped yet another dime?

Gradually the story unfolded. Apparently Mark D’ull, the owner of Best Parts, a video company, had been there earlier allegedly brandishing a knife and making death threats. I had the opportunity to talk to Suzanne, the employee that D’ull threatened. It seems that D’ull has been living with billionaire Kirk Kerkorian’s daughter, Tracey. As was Suzanne, who until over the weekend had been in D’ull’s employ since last May. Suzanne has worked in the adult business 23 years and started with Bill Amerson.

It was Suzanne’s opinion that D’ull was taking advantage of Tracey because of the Kirkorian money, told her so and D’ull didn’t like the idea she was butting in.

“Maybe I got a little too close,” says Suzanne. “But Mark wasn’t doing right by her.” Matters apparently came to a head and D’ull both fired Suzanne and kicked her out of the house. Suzanne found another job by making some calls and D’ull evidently discovered where she was hanging her hat. According to what Suzanne told me, D’ull called her three times Tuesday morning, calling her a bitch and telling her he was coming to kill her. D’ull showed up about 10:30 am and was locked out of the offices before he could get in. That’s when Suzanne called the cops and D’ull took off after pacing outside for maybe an hour.

“It makes me feel bad that this idiot came here,” said Suzanne after making a statement to the police. Suzanne goes on to talk about how D’ull keeps his money stashed away in safe deposit boxes.

Apparently D’ull met Kirkorian’s daughter on the Internet. At the time, she was living in the Beverly Hills Hotel with a husband from an arranged marriage.

“Mark knew how to push her sexual buttons,” says Suzanne of his relationship with Tracey Kirkorian. “He bragged about how he got her for the price of a $12 turkey sandwich. Her divorce will be final next month and Mark thinks he’s going to marry her.”

During my conversation with Suzanne, she got a call from Tracey telling her that D’ull had just been arrested and taken to a mental ward.

“Remember, I love you and care about you,” Suzanne is telling Tracey in an effort to calm her.
