VULCAN, Alta. - A weekend boat trip turned tragic for a man and woman on McGregor Lake in southern Alberta.

Police say the pair in their 30s set out in a boat Sunday, and that the boat was later spotted adrift.

The woman was found dead near the shore of the lake, about 150 kilometres southeast of Calgary, and searchers spent Sunday night and all day Monday looking for the man.

Police say the woman wasn't wearing a life jacket, and none was found on the boat.

RCMP called off the search for the man, saying all areas have been checked.

No names have been released.
