"If you can come back to me and stop all the craziness, we can have a wonderful life ... your forgiveness, trust and loyalty is all I need right now and when your love for me grows and our lives are heading in the right direction, I'll truly feel complete," Jenkins wrote. "I will never leave you. I only want you."
Fiore returned to Jenkins, and the reunited couple headed off for a poker tournament together. On Aug. 13, they checked into the L'Auberge Del Mar Hotel in San Diego.
Two days later, Fiore's body was found inside a suitcase, left inside a Dumpster, her fingers and teeth removed.
"Ryan Jenkins is an animal," Fiore's ex-boyfriend Robert Hasman said. "What he has done to Jasmine is unspeakable."
Friends speculate that Jenkins discovered text messages between Fiore and Hasman and flew into a jealous rage.
"He beat her up, choked her, killed her, realized what he did, tried to cover it up, panicked ... he mutilated her, and threw her in the trash," an emotional Tonja Monroe, Fiore's stylist and friend, told ABC News. "No woman belongs in the trash -- I don't care what kind of person they are, nobody deserves to die like that. Nobody."
Brad Garrett, a former FBI profiler and an ABC News consultant, said, "It is the kind of case that would get prosecuted for capital murder because it's so, it's so horrendous. These horrible acts of removing her fingers or pulling her teeth, he's only thinking about this is going to cover it up for me, so someone else will get blamed for this Jane Doe in a Dumpster."
Jenkins was charged with Fiore's murder, and the U.S. Marshall's Service offered a $25,000 reward for his capture.
"There will be no stone unturned and we'll look under every rock for him," Chief Inspector Thomas Hession said at the time.
The hunt ended a week after Fiore's body was found, when authorities discovered Jenkins hanged in a motel room closet in Hope, British Columbia. It was an apparent suicide, authorities said.
"Probably what went through his mind is, 'I just cannot get out of this,'" Garrett said. "Because, quite possibly, this stepped over the line for him, that he had done something that his psyche couldn't even deal with. And so he gets to Canada, he's alone, he starts thinking, actually, maybe he even had visions in his mind as to what he had done to this woman and he couldn't take it any longer."
Now, both principals in the rocky romance are dead, and two families are grieving. "My condolences to Jasmine's [family], deepest, deepest condolences to their loss as well," Nada Jenkins, the suspect's mother, told a Canadian reporter. "I can't deal with this right now.
"My son is innocent. I think he panicked, and I'm just dead inside. I'm devastated, what can I tell you. I love him, he's my only child. I can't have any phone calls anymore."
Jenkins' father, Dan Jenkins, told the The Calgary Sun, "He was kind. He was sweet. He was innocent ...
"Something down there in these last four months, including this girl, just destroyed him. ... I advised him 50 times to get rid of that relationship."
It turned out Fiore had some secrets of her own.
She'd had a first marriage few people knew about, to a man named Mike Cardosi. A mutual friend, Grady Huber, showed ABC News pictures of the wedding.
