THE final moments of an outdoor-loving couple who were mauled to death by a grizzly bear have been revealed by heartbroken family members.

Doug Inglis and Jenny Gussee, both 62, used a full can of bear spray during a fight for their lives in Canada’s Banff National Park, west of Calgary, Alberta.

On Friday at 8pm, Doug’s uncle Colin received an SOS that made his heart sink.

“I got a call from their Garmin that said, ‘Bear attack bad,'” Colin told the Calgary Herald.

“The alarm bells were going off, ‘this is not good’ — that means there’d been some engagement.”

He and Doug tried to keep tabs on each other during outdoor excursions, so he knew that his nephew was out camping in a remote area with his common-law wife Jenny.

“You’re completely helpless to know what’s going on,” he said.

Parks Canada officials got the message too, and launched a mad search for the pair, but overcast weather slowed their pace.

They attempted to fly a helicopter, but had to ground it and raced through the park all night on ATVs instead, Colin said.

At 2am, they finally got to the campsite and discovered Doug, Jenny, and their seven-year-old border collie Tris all mauled to death.

In a heartwrenching final scene, Colin believes they were likely relaxing and reading in the tent when the ferocious female bear descended on them.

“Their tent was crushed and their e-readers were open, they were both discovered in their stocking feet,” Colin said.

Evidence showed that one of them likely left the tent to fight the bear to the bitter end, Colin said.

He continued, “It’s possible one was on the outside trying to tend off the bear while the other was in the tent sending the message.”

“In their words, the bear was intent on killing them.”

‘EXPLORED THE WORLD’

Colin remembers the pair as accomplished and passionate about wildlife and nature.

Both worked at the Agriculture and Agri-Food Research Centre in Lethbridge with Doug working as a research scientist while Gusse was a lab technician.

“Jenny was on the ground in that research, carrying out that research… there’s holes in that lab right now,” said Colin

“They approached everything in their outdoor pursuits the same way they approached that science — the mapping, the planning, the food, everything.

“They did everything right, but bad things happen.”

The couple was familiar with the area where they camped as they made trips twice a year.

Next year, they were planning on retiring and spending even more time together in nature.

“Doug would have published half a dozen papers a year, for a number of years,” said friend Ron Teather, who added that the couple were both interested in reducing the risk of bears.

“He was talking about this new bear-proof food cache they’d acquired — they were always concerned when traveling in the backcountry but you have to accept the fact some things are beyond your control.”

Wildlife officials chased down the predator and found a skinny female grizzly who immediately started acting aggressively.

They euthanized her and are currently examining the animal’s body to see if there were any factors that could have contributed to the attack, like if the bear was sick or malnourished.
