STOCKHOLM, Sweden — Swedish police say they've cleared a man who was arrested for allegedly killing his wife after deciding the culprit was most likely a moose.

Police spokesman Ulf Karlsson says "the improbable has become probable" in the puzzling death last year of 63-year old Agneta Westlund. She was found dead after an evening stroll in the forest.

According to news reports, the victim's husband Ingemar Westlund, was jailed for 10 days. The case against him was dropped in January.

Karlsson declined to give details of the case Saturday, saying a news conference would be held Tuesday.

The tabloid Expressen says hairs and saliva from a moose -- aka a European elk -- were found on the victim's clothes. Police would not immediately confirm that.
