In the meantime, his dadisn't sitting still.

"I'm always looking, looking, lookingand trying to look for clues that he's still around, looking for maybe a jacket, or sweater, or socks or a bag," hesaid.

MattinasJr. is described as:

• Five-foot-10 with an athletic build.
• Black hair, brown eyes and a thin moustache with slight sideburns.
• Lastseen wearing a camouflage-patternor beige jacket, blue jeans andbrown boots,and possibly carrying a black Under Armour tote bag and/or brown backpack.

He was originally reported missing to the Nishnawbe Aski Police Service (NAPS) in late March. Since then, the investigation has been taken over by Ontario Provincial Police's North East Region.

OPPConst. Kyler Brouwer of the James Bay detachment told CBC News on Thursday that there have been no substantial updates on the case since the last policenews release on April 25.

"The investigation is being led by the James Bay Ontario Provincial Police (OPP) Crime Unit with assistance from the North East Region Emergency Response Team (ERT), North East Region Canine Unit, OPP Aviation Services, and OPP Remotely Piloted Aircraft System (RPAS). These specialty units have conducted searches of the area, however the missing person has not been located," Brouwer said in a follow-up email to CBC News Friday morning.

"The OPP is continuing to actively investigate this missing person case, and urge anyone with information to contact the police or Crime Stoppers."

Thunder Bay is some500 kilometres southwest of Constance Lake, about a 5-hour drive along Highway 11 to Highway 17. Nearly 900 people live in the Oji-Cree community, which is part of Treaty 9.

Support from Cat Lake First Nation

On the day of MattinasJr.'s disappearance, there was a snowstorm.

Since then, his dad has been out regardless of the weather. He leaves home inthe morning andlooksaround Constance LakeFirst Nation before coming back to pick up his other sons from school. Then, he's back out again.

Now that it'swarmer outside, he's been going out on an ATV.

"It's very scary sometimes, being out there by yourself," he said about searching the bush.

At the end of April, a team of trackers from Cat Lake First Nation arrivedto aid the family's search efforts. The trackersshowed the family how to document their searches using GPS data and the CalTopomapping app.

The Cat Lake team is expected to return to Constance Lake next week. Mattinas Sr. said the family is grateful for their support.

Still, the family hopes to get more boots on the ground as they conduct their own searches. A Facebook group called Search for Dean JR Mattinas had 140 members at publication time.

Searching thehighway a 'challenge': NAN

Constance Lake is part of Nishnawbe Aski Nation, a political-territorial organization that represents 49 First Nations across Treaties 9 and 5.

Michael Heintzman, NAN's director of communications, provided an emailed statement to CBC News on Thursday about Mattinas Jr.'sdisappearance.

The search has been very difficultand we acknowledge the family's frustration.- Michael Heintzman, NAN's director of communications

"We are very concerned about Dean Mattinas and we pray for his safe return.Searching this long stretch of highway has been a tremendous challenge.The search has been very difficultand we acknowledge the family's frustration," Heintzman said

"Our crisis response team has supported search efforts by providing supplies including reflective vests, flashlights, maps, hats, socks, mitts, radios, groceries for meals for the searchers and the family."

Heintzman said NAN's crisis co-ordinators assisted with a search from April 10 to 13 and set up a command centre at the community hall. Since then, NAN has "co-ordinated ongoing supports with community staff and Matawa First Nations Management, while others have worked directly with the family."

"NAN has supported many searches for missing community members across northwestern Ontario. Our crisis response staff do the best they can to respond and support when requested with limited resources," Heintzman said.

'He's a family boy'

It is unlike MattinasJr. to not be in contact with his family, said Tracy Bois, Mattinas Sr.'s partner.

"He's a family boy," she said. "He was working. He was independent. He was on the right track."

This week, Mattinas Sr. and his youngest sons spelled out a message in a field with pieces of woodthatsays: "Dean WRU (where are you)."

The family also lit a sacred fire in his honour.

After weeks of searching, Mattinas Sr. said his eyes have started to play tricks on him. His sisters have also been involved in the searchand it's been exhausting for everyone.

"Just like looking for a needle in a haystack," Bois said.
