Ryan Jenkins' half-sister may have reportedly helped him elude authorities after he was charged with murdering Jasmine Fiore.

A silver PT Cruiser with Alberta plates that matches the description of the vehicle allegedly seen dropping off the now-dead accused murderer at a secluded Canadian motel last Thursday night was located in the parking garage of a condo where Jenkins' half-sister Alena resides, The Vancouver Sun reported Wednesday.

In addition, The Sun reported Alberta vehicle records show a silver 2001 PT Cruiser is one of several vehicles registered to Jenkins' father Dan. 

While Dan's neighbors told The Sun that the vehicle had been stored in the parkade underneath his Calgary, Alberta condominium for "an extended period of time," it had recently been moved.

Investigators have declined to comment on who owns the PT Cruiser witnesses allegedly saw the woman driving.

"I won't speak to that at all," Cpl. Norm Massie of the federal border integrity program told The Sun.

Jenkins -- who appeared as a suitor on VH1's since canceled Megan Wants a Millionaire reality series -- was charged with murder last Thursday in the death of Fiore, a 28-year-old swimsuit model whose body was found August 15 stuffed in a suitcase in a Buena Park, CA trash can.

Police alleged Jenkins removed Fiore's teeth and fingers prior to disposing of her body, presumably to hinder efforts to identify her, however authorities used the serial numbers on her breast implants to identify the body. A preliminary coroner's report showed Fiore was strangled.

Jenkins subsequently became the focus of an extensive manhunt on the U.S. and Canadian border after his car and an empty boat trailer belonging to him were found abandoned at a marina in Blaine, WA and a man matching his description was seen arriving 15 miles away in Point Roberts, WA on a boat registered to him last Wednesday.

Jenkins' father and stepmother Karen Stanwood previously co-owned a home in Point Roberts, according to The Sun, and Dan's ex-wife Sandra indicated he was driving a leased PT Cruiser when they first met in the former couple's divorce records.

In addition, Alena's mother currently lives in Point Roberts, according to Canada's CTV television network.

Point Roberts is located roughly 100 miles from Hope, British Columbia -- which is where Jenkins was allegedly checked into the Thunderbird Motel last Thursday evening by the unknown woman, who paid $140 cash (Canadian) for a three-night stay before another motel guest saw her leave shortly thereafter.

Jenkins was found dead on Sunday after allegedly hanging himself in the motel.

Thunderbird Motel manager Kevin Walker previously described the woman as blonde, in her early twenties and "naturally pretty, one of those wholesome little ladies," adding she and Jenkins pulled up in a silver Chrysler PT Cruiser with tinted windows and license plates from Jenkins' native Alberta.

According to her profile on ModelMayhem.com, a popular modeling website, Alena is 5'7", 125-pound 19-year-old with long blonde hair and blue eyes.

Royal Canadian Mounted Police spokesman Sgt. Duncan Pond told reporters during a Monday news conference that authorities do know the identity of the woman who allegedly checked Jenkins into the Thunderbird Motel -- however they have yet to publicly reveal it.

"This is not someone that we feel is a risk to the public safety.  We are not seeking the public's assistance in locating this female," Pond told reporters.  "We will still have to try and protect the integrity of the investigation and not disclose details of the information that we're gathering at this time."

In addition, Pond stated that authorities believe Jenkins and the women "knew each other" and had a "past history."

"But we don't want to go into specific detail as to the relationship.  At this time we don't think it would be appropriate to comment on whether or not it was an associate, a friend or family," said Pond. "We have no information at this time to believe that there were any threats or coercion applied to her, but any kind of statements like that, those are very preliminary statements. The investigation is still ongoing."

While Dan has adamantly denied he spoke to his son before his alleged suicide, the father has also proclaimed Jenkins' innocence in the murder until more evidence is provided.
