The family members of Lyle and Marie McCann have a new glimpse of the man considered a suspect in the couple's disappearance.

Travis Vader answered to 13 charges, from arson to theft over $5,000 in a Mayerthorpe courtroom Tuesday. A preliminary hearing was held on charges unrelated to the couple.

He's never been charged in connection to the McCanns' disappearance, only named a suspect.

Alberta Sheriffs brought Vader to court under high security. His ankles were shackled and the prisoner van was parked very close to the courthouse to limit his chance of escaping.

CTV News was there as Vader was escorted out of the courthouse, but he would not respond to the one question many want answered.

"Do you have any idea what happened to the McCanns?" asked CTV's Bill Fortier.

But Vader remained silent. The family of Lyle and Marie were shown the video of Vader exiting the courthouse.

"This is the first sort of clear video of him that I've seen," said the couple's son, Bret McCann. "Looks like he knows something. Maybe I'm just reading too much into it. Looks like he knows something -- looks like he's smug about it."

Bret says he has to question why Vader chose to remain silent when he was given a chance to speak out.

"Why didn't he say 'nothing, I know nothing'? Why wouldn't he be screaming from the rooftops, 'I don't know anything about this'"?

The McCanns were last seen back on July 3rd, 2010 when the couple left for a holiday in B.C. in their RV.

On July 5th, an Edson RCMP officer came across the couple's burning RV. On July 16th, their missing SUV was located.

Mounties continue to investigate, but they haven't charged anyone and the McCanns haven't been found.

"Maybe I'm naive, but I have a lot of faith in the RCMP," said Bret.

Bret says while watching the video of Vader he can't shake his hunch.

"Whatever pain my parents went through, you know, that guy was there."

Vader was arrested last July by RCMP at a rural residence near Niton Junction. On August 31st, police officially named him a suspect in the case.

The 13 charges Vader answered to in court Tuesday, are just a fraction of the charges he faces across the province.

By law, CTV cannot share the details of Tuesday's preliminary hearing. But the judge did decide to proceed to trial on six counts related to alleged arson and theft.

Vader remains in custody.
