Police in Barrie, Ont., are resuming their search for missing 15-year-old Brandon Crisp despite having no new tips in the case.

Crisp went missing on Oct. 13, Thanksgiving Day, after getting into a fight with his parents over his incessant video-game playing.

An intensive police search, supplemented by a parallel effort byvolunteers, had failed to come up with any solid leads.

After calling off the search earlier this week, police say they want to double-check one area as a precautionary measure.

"The area is a rural area and there's a lot of thick, dense bush in there so we're just trying to get into some of those areas one more time," Sgt. Dave Goodbrand of the Barrie Police told CTV on Friday.

Goodbrand said investigators will also be canvassing the near the trail where Brandon last went missing.

"(We're) hoping to get people that may walk that trail on a regular basis... (who) may have some crucial piece of information that we can use," he said.

The boy's father, Steve Crisp, told CTV Newsnet on Friday afternoon that the path where Brandon went missing is a busy pedestrian area.

"There would have been a lot of cyclists, a lot of people walking their dogs," Crisp said, of the day Brandon went missing.

But only "one or two" people reported seeing his missing son that day, he said.

Local police have expanded their search beyond the part of the bike trail they originally searched, he said.

Brandon's mother, Angelika Crisp, said her family is taking life "one day at a time, one hour at time" since his disappearance.

"It's very difficult," she said.

His parents reiterated their belief that their son had made contact with a fellow Xbox video-game player.

"Hopefully he's just afraid to come home," Angelika Crisp said. "But there are other scenarios that we think might be a little more realistic, and that's that he's befriended someone on this game and he's with them."

His father said that "99 per cent" of Brandon's online Xbox contacts were video-game players from the United States.

"This causes another problem," he said. "There is a possibility that he's contacted someone or met someone from the United States."

Meanwhile, police have also taken their search for Brandon south of the border, enlisting the help of a popular crime TV show.

"America's Most Wanted" is now featuring the case of 15-year-old Brandon Crisp on their website.

Officials at the show say they are monitoring the case and might feature it on their show if police believe the avid gamer might have made his way to the U.S.

"We also have to consider that there's that possibility that he went to the United States," Goodbrand said.

"...We just want to do everything we can to ensure we cover as much ground in the event that Brandon did leave the area of Barrie."

Brandon is described as male, white, 100 pounds, 5'2", with short sandy blond hair.

When Brandon was last seen, he was wearing a yellow and grey jacket, a grey American Eagle-brand hoodie, blue jeans, white runners with a camouflage stripe on the sides. He may also be carrying a yellow and grey back pack.
