Ryan Jenkins, Jasmine Fiore

Police said they found blood and evidence of a violent struggle between slain model Jasmine Fiore and her ex-husband, former VH1 reality star Ryan Jenkins, inside her abandoned car.

Though Fiore's white Mercedes-Benz appeared to have been wiped down, investigators found blood on the passenger seat, backseat and windshield, Buena Park Police Sgt. Bill Kohanek said in a news conference Thursday. "There's evidence of a struggle inside the vehicle and head injuries — particularly broken noses, those types of things — tend to bleed a lot," he said.

However, police said they are unable to determine whether Fiore was killed in the car or somewhere else. Blood stains were also found on the patio of the San Diego-based L'Auberge Del Mar hotel room Jenkins and Fiore checked into on Aug. 13, police said. Fiore's body was found stuffed inside a suitcase in a trash bin on Aug. 15. Her fingers and teeth were removed.

Due to traces of twigs and grass in the undercarriage of the Mercedes, police said they believe Jenkins took the vehicle off-road at some point. They are still combing the area to locate Fiore's fingers and teeth.

An old letter written by Jenkins to Fiore was also found in the glove compartment of the vehicle, in which Jenkins expressed jealousy, police said. "[The relationship] had a lot of tension," Sgt. Frank Nunes said. "There was a whole lot of jealousy on his part."

Jenkins, who was charged with Fiore's murder, fled to Canada and was found hanging in a British Columbia motel room on Sunday. Authorities said they have not found evidence of anyone aiding Jenkins' escape to Canada. "We haven't uncovered any information that he had any help," Kohanek said.
