Suspect in Calgary girl's disappearance not co-operating; has criminal history

CALGARY — A suspect arrested in the disappearance of a five-year-old Calgary girl is giving "zero co-operation" to investigators, police said Thursday as officers scoured a rural area east of the city.

Insp. Don Coleman said Thursday the man is believed to be the same one witnesses saw Monday with a girl matching Taliyah Marsman's description.

The man and girl were in the same Calgary neighbourhood where Sara Baillie's body was discovered Monday night in the basement suite she shared with her daughter.

Police believe the man and the girl left a car belonging to Baillie, got into a grey sedan and drove off. Coleman said the sedan was seized in a strip mall parking lot on Wednesday night and the driver was arrested. The car was being examined by the forensics unit.

Coleman said Baillie, 34, knew the suspect, as did Taliyah's father, Colin Marsman. He also said the suspect is known to police and has a extensive criminal background with some violence. 

Police have not closed their eyes to the possibility of other suspects, he said.

Meanwhile, between 50 and 75 city police and RCMP officers were searching for clues in a rural area east of Calgary on Thursday.

The officers, wearing bright yellow vests, were trudging through canola fields of the same vibrant hue and combing through tall grass with poles.

The groups made their way deliberately along gravel side roads, stopping to talk to property owners and lingering when they came across a culvert or bridge.

Coleman acknowledged that the rural search "does have a more ominous tone to it" but added it shouldn't be viewed negatively.

"Information that comes to light through several investigative strategies led us to believe that this individual was briefly in that area," he said.

"We've searched other premises in the last few days. This rural area is no different."

A stuffed animal was found by searchers, but police have no idea if it's significant.

Margaret Orr, who lives on a rural property on the edge of a golf course, said police came by and asked how long she and her husband have been living there and if they'd seen or heard anything suspicious.

Orr said she had looked through her barn, greenhouse and other buildings on her property and would continue to keep an eye out.

An Amber Alert was still in effect Thursday and Coleman said police expect to find Taliyah alive.

"There has been nothing to indicate the status of that has changed."

On Wednesday, Coleman said the girl seen by witnesses around midday Monday had a reddish suitcase, suggesting whoever had her intends to look after her.

Investigators have also said footage from a closed-circuit camera shows Baillie and her daughter at a Dairy Queen around suppertime Sunday. Baillie appears to be speaking with a man and a boy. Police have yet to identify the people in the footage and have posted still photos of the exchange on the City of Calgary's website.

Taliyah's family was "doing exactly as expected," Coleman said.

"They are very ... upset. They want Taliyah safely returned. They've lost their daughter, their niece, and they're just hoping that at least Taliyah can be returned safely."

Her father has also put out a plea for whoever has Taliyah to "do the right thing."
