A man who looked like the husband of slain swimsuit model Jasmine Fiore was detained overnight in Toronto, but was released when it was determined he wasn't the fugitive reality TV star Ryan Alexander Jenkins, the prime suspect in his wife's grisly killing.
Jenkins, 32, is a Canadian citizen who police believe fled to his home country after the former Playboy model's body Canadian police intensified their search for Jenkins today, after a nationwide provisional warrant was issued for his arrest Friday, after his car and boat trailer were found in northern Washington State, and his ski boat was found at a marina in Port Roberts, Wash., walking distance from the Canadian border.
"We're leaving no stone unturned, but we have to play our cards close to our chest right now," Royal Canadian Mounted Police Sgt. Duncan Pound said today.
The search was centered around Vancouver and British Columbia, Canadian Public Safety Minister Peter Van Loan said.
Late last night, a traveler on a flight from Vancouver who looked like Jenkins was taken into custody at Toronto's Pearson International Airport.
Staff-Sgt. Keith Brodie of the airport division of Peel Regional Police confirmed that authorities had detained someone who matched Jenkins' description, but said that man was questioned and released, once it was confirmed he was not Jenkins.
"Obviously with a case like this where there's a great deal of media attention and publicity, there tends to be a higher number of possible sightings and people that are trying to be helpful," Sgt. Duncan Pound of the Royal Canadian Mounted Police told ABC News' "Nightline" Friday.
She was subsequently identified by the serial number on her breast implants, The Associated Press reported Friday.
If Jenkins is arrested in Canada, he will only be returned to the United States if prosecutors do not seek the death penalty.
A source that was with the couple shortly before Fiore died told ABC News about the couple's "blow-out fight in front of everyone" in San Diego overnight Aug. 13-14 -- the last night she was seen alive.
"Jasmine was playing poker with a big group of friends at the Hilton Hotel," the source said. "She was being very rude and kept putting Ryan down. It was really awkward. She has a cutting sense of humor. He was getting really angry, and it totally set the tone for the rest of the evening."
"At about 1:30, they went up to their room to continue fighting," the source also said.
Jenkins, a television contestant who appeared on VH1's "Megan Wants a Millionaire," called police to report that Fiore, but not until hours after his wife's body had been found.
Sheriff's officers in Whatcom County, Wash., found Jenkins' car with an empty boat trailer attached Wednesday night, and then Thursday morning found his boat at a marina 10 miles away. Authorities said they believe Jenkins walked across the border into the Canadian province of British Columbia.
Jenkins was arrested in June on domestic violence charges after allegedly hitting Fiore.
In 2007, he was also sentenced to 15 months' probation on an unspecified assault charge, according to the Alberta, Canada, Ministry of Justice.
