Vancouver police are searching for signs of a missing woman in a park where her vehicle was seen on the day she disappeared.

Su Yi Liang, 37, was last seen Jan. 8, and was reported two days later, after failing to pick up her children from school.

Liang's 2014 BMW i3 was found the day after her case was opened in the parking lot of the Rupert Park Pitch and Putt.

In an attempt to track her movement in the days before she disappeared, police have collected evidence that suggests her grey electric car was seen at New Brighton Park on Jan. 8.

They believe her vehicle was at the park just after noon, while Liang herself went missing before noon. Officers suspect someone else was behind the wheel when the vehicle was captured on traffic cameras that afternoon.

Police have said previously that they have evidence that has convinced them to believe she may not be found alive.

Officers searched her home last month and at one point took a man in for questioning, but he was released without charges.

Investigators returned to the park Wednesday to look for further signs, and to ask members of the public if they saw anything that day.

"It's important we speak with anyone who may have seen her electric car in the parking lot," Const. Jason Doucette said.

Officers were seen searching a taped-off area near the waterfront on foot. A dive team was also present at the park, searching part of the Burrard Inlet near the park's northern edge.

"We're not ruling anything out at this point," Doucette said.

"That's why we've brought our divers, we've brought out our search and canvass people. We're looking for any piece of information that will help piece this together."

Anyone with information on Liang's whereabouts and her activities leading up to Jan. 8 is asked to contact police. Officers would also like to speak to anyone who may have seen someone driving her i3 before it was found Jan. 11.

Tips can be left with the VPD's Major Crime section at 604-717-2500, or through Crime Stoppers anonymously at 1-800-222-8477 (TIPS).

Liang has been described as Asian, 5-3 and about 120 pounds. She has black, shoulder-length hair and wears glasses.
