EDMONTON - Bret McCann had a simple message for his missing parents at an RCMP news conference more than a week after their burning motorhome was discovered west of Edmonton.

"We know you're out there. You may be hurt," McCann, his voice quavering with emotion, said Tuesday. "But we're looking as hard as we can for you."

Police are calling the mysterious disappearance of Lyle McCann, 78 and his wife Marie, 77, "extremely suspicious." Their motorhome was discovered engulfed in flames in a remote wooded area near Edson, Alta., July 5.

RCMP and the family believe a missing light green Hyundai Tucson SUV the couple were towing behind their RV may be the key to finding out what happened to them.

Investigators said they are rechecking an area near where the burned motorhome was found, hoping for clues. An aerial and ground search of the region is underway and police have called in an arson expert to go over the charred remains of the motorhome.

The wreckage was found two days after the St. Albert couple left on a trip to B.C.'s Fraser Valley. The couple was last seen July 3 when a video surveillance camera at a gas station in their hometown recorded them filling up.

NOVA.SCOTIA (CBC) - A deer caused a commotion in a Tim Hortons store in Glace Bay, N.S., over the weekend.

The deer smashed through the front window of the Cape Breton coffee shop on Commercial Street early Saturday around 5:50 a.m., frightening employees who were working in a back room.

The employees thought thieves had broken in and called Cape Breton Regional police.

Sgt. Jerome Kelly said the two employees had no idea it was a deer that crashed through the glass.

"They could hear the smashing and banging and figured it must have been an individual doing a break-in," he said.

Officers found a deer trapped between two glass doors at the front of the building.

"The deer was continually banging at both doors, but it was too small to get enough momentum to break the glass. But he was continually banging it, which made staff feel that there was somebody in there firing things around."

When police arrived on the scene, Kelly said, they were able to get a key to the front door and let the deer out.

The deer ran off with only a minor cut to its back leg, he said.

CALGARY - Calgary Stampede officials say they are upset by the deaths of four horses and a serious injury to a rider in the first few days of the annual rodeo, but at least one animal welfare organization says it's all "depressingly predictable."

Three horses died on Monday alone.

The day started when a horse in a chuckwagon team suffered a fatal heart attack while doing routine training exercises. Just a few hours later, during the novice saddle bronc event, a horse without a rider bucked so hard it broke its back and had to be euthanized.

"It is unusual and it is unfortunate," said Stampede spokesman Doug Fraser. "The death of the bucking horse was really a chance phenomenon."

Horses buck in the field every day and don't get hurt, Fraser said.

CALGARY (CBC) - A short but intense thunderstorm pelted parts of Calgary with hail the size of golf balls, high winds and heavy rain, damaging homes, buildings and vehicles.

A severe thunderstorm warning for the city ended after a few hours Monday. Tornado warnings for Drumheller, Wheatland County and other southern Alberta areas were also lifted after a few hours.

Sandy Massey, the warning preparedness meterologist with Environment Canada, said the storm moved so quickly there wasn't enough time for the agency to issue a warning before the hail hit Calgary.
