A massive search by residents, volunteer firefighters, police officers and police dogs is underway for a two-year-old boy who was last seen playing outside his home in the town of Austin, Man., at approximately 6 p.m. Tuesday.

Chase Martens is described as two and a half feet tall, 30 lbs, with blue eyes and light brown hair. He was last seen wearing a blue jacket, blue splash pants, a red hat and boots that light up as he walks.

Mounties are asking people travelling in the area of Highway 34 and Austin to be on the lookout for Chase.

"We are thinking about all possibilities right now. We are not ruling out any kind of avenues of investigation," RCMP Sgt. Bert Paquet told CTV Winnipeg.

"At this point in time, the focus of our investigation is to find Chase safely, and bring him home."

Anyone with information about his disappearance is asked to call 911 or their local police department.

More than 300 volunteers have joined the search for Chase, as well as several local fire departments.

Delphine Blair has offered her help because she has two-year-old granddaughter, and hopes others would do the same for her.

"Oh my goodness, if that was my granddaughter I would want someone to come search for her too," said Blair.

"I hope they find him … I mean there's so many people here you would think they would find him by now."

Cameron Campbell travelled for more than an hour from Alonsa, Man., to help out.

"You always hope for the best, but then there's always that thought in the back of your mind, so who knows," said Campbell.

Some searchers are combing the area surrounding the family's home using ATVs and on horseback, but most are on foot.

But so far there has been no sign of Chase.

"(It is) disheartening, kind of, because you don't see nothing. There's just nothing there," said volunteer Janet McGregor.

Austin is about 110 kilometres west of Winnipeg.
