A former reality star police hope to question in the death of his former wife, ex-swimsuit model Jasmine Fiore, has crossed into Canada on foot, Los Angeles news station KTLA reported, citing police.

Ryan Jenkins, a contestant on VH1's Megan Wants a Millionaire, is sought for questioning in the death of Fiore, whose body was found stuffed inside a suitcase behind a Buena Park apartment complex.

Fiore, 28, was last seen with Jenkins, 32, on Friday night at a poker game in San Diego, according to The Associated Press. Jenkins reported her missing Saturday night to the Los Angeles County Sheriff's Department, police said.

"At this point, he's merely a person of interest, simply because of the suspiciousness of his disappearance. We can't find him," Buena Park Lt. Gary Worral said. "We find it suspicious that with all the media coverage that he has not made himself available to us."

The death and search have derailed VH1's Megan Wants a Millionaire. Jenkins has appeared in all three episodes that have aired so far of the reality dating, which is similar to The Bachelorette but includes wealthy suitors. On the show, Jenkins was identified as an investment banker.

"Given the unfortunate circumstances, VH1 has postponed any future airings," the network said in a statement. "This is a tragic situation and our thoughts go out to the victim's family."

The show completed production in March.

The victim's mother said the two, who were briefly married, had been fighting and that he was jealous of her ex-boyfriends. 

Jenkins has a criminal history in his hometown of Calgary, Alberta and was sentenced to 15 months of probation in January 2007 on an unspecified assault charge, according to the Alberta, Canada Ministry of Justice.
