The 40-year-old actress came home with Spector from a club on the Sunset Strip one night and ended up dead, just inside the front door of his mansion, from a single gunshot wound in her mouth.
As Spector began serving a prison sentence of 19 years to life, the famed "Wall of Sound" producer left plenty behind, most notably, an incomparable pop music legacy and a young blond Pennsylvania native named Rachelle, who now dwells in the house where Clarkson died. She is the 29-year-old Mrs. Phil Spector.
Rachelle Spector is the vice president and CFO of Spector's music companies. She oversees a catalog of pop hits that generate a seven-figure yearly income. She also orchestrates Spector's appeals. And she is 40 years younger than her famous husband. While some may snicker at their romance, she proclaims the innocence of her 69-year-old spouse.
"I mean, I feel like I'm on a mission. This is far greater and a bigger challenge than I ever imagined. But it's totally positive, protesting my husband's innocence, restoring his name, honor, legend," she told ABC News' Chris Connelly.
She attended her husband's trial each day, and her advocacy got people's attention, as did the hairstyles she cooked up for her husband, like the frizzy Afro he wore to court one day.
When asked about her husband's mood during the trial, Rachelle said, "Well, it's like going to a hell hole. I mean, they're accusing you of the worst crime possible, and, you know, you're sitting there innocent and nobody wants to believe you."
Now, Rachelle wants the public to believe her.
"It's an unfortunate circumstance and I'm very sad for the family, but I have to be positive and I have to move on. This is our home," she said, standing in the foyer of her home, the spot where Clarkson died.
It sure isn't the home she imagined eight years ago, when at 21, she beat it out of Beaver Falls, Pa., one afternoon, heading for Hollywood. She dreamed of life as a rock singer in leather pants.
"Well, I wouldn't call anything success," she said about her first years in Los Angeles. "I would just call it learning the ropes and working my ass off to get by at that point. And I mean, of course, there were a couple of times where I thought I would have had to move back home. I kept focusing and being really positive and putting myself out there. And just stuff started happening."
In the fall of 2003, Rachelle was introduced to Spector at Dan Tana's, a music business hangout, while heading for the ladies' room.
"I ended up not even being able to go to the restroom! But one main thing that my husband did say that night, I remember him saying, 'Timing is everything,'" said Rachelle. "You could have all the luck in the world and it's all about being in the right place at the right time."
Her own timing was ideal. She was waiting tables to finance her music aspirations. He was a music biz big shot with a fondness for blondes and a forthcoming indictment for homicide. They talked until 6 a.m. the next morning.
"It was so funny 'cause he looks up at me and he's like, 'May I kiss you?' And I'm like, 'No,'" said Rachelle laughing. "Like, no one has probably ever turned him down before, like, ever."
