The search continued Friday in Lennox Island, P.E.I., for 28-year-old Jamie Sark.
Sark was last seen Saturday between 11 a.m. and noon near Mosquito Path in a wooded area of the island on P.E.I.'s North Shore. He was reported missing Wednesday.
The Prince District RCMP said Thursday some of Sark's personal items were found near a water tower on the island, which is in western P.E.I.
Sark is described as being nearly five feet 11 inches tall and weighing about 130 pounds. He usually wears prescription glasses, and was last seen wearing a black T-shirt, blue jeans and a black hat.
Police say Sark does not have a history of leaving without informing anyone.
Volunteer crews from P.E.I. Ground Search and Rescue began searching on Lennox Island starting in the area where Sark was last seen, then kept expanding the search area around it, both on foot and on the water around Lennox Island.
Friday, four six-person teams searched the community, and RCMP said a helicopter was also expected to arrive Saturday. Teams may wrap up the ground search by the end of day Friday.
"He might not be in Lennox right now," said Sgt. Neil Logan with Prince District RCMP. "We're hoping if somebody knows where he is, we'll get a tip."
"I feel very confident that everything is being done that we can do to find this young man," said Lennox Island First Nation Chief Darlene Bernard.
"We're distraught, right, but we're trying to keep really positive."
She said band councillors are supporting the family, and community members on the island are working to keep search teams fed.
Abegweit First Nation, P.E.I.'s other band, is also providing a team to help, Bernard said.
RCMP said they had had some tips that came in outside of Lennox Island that they followed up, but those did not lead anywhere.
Anyone who has seen Sark since he went missing or has information on his whereabouts should contact the RCMP at (902) 436-9300.
