CLOVIS, N.M. (AP) -- Salmon did the trick. The initial suspicion was that a homeless person stayed in Clovis' public library past closing time and triggered the alarm system's motion detector. But according to the Clovis News Journal (ttp://bit.ly/1nvCCWR), a search by police and librarian Margaret Hinchee for more than an hour that night was fruitless. It happened the next few nights too. But then a custodian reported seeing a cat, and library staff spotted clues such as scratches in plant soil. A check of video footage confirmed there was a cat in the library. So the librarians put salmon in a cage and left one night. When they returned a half-hour later, the cat was in the cage. The cat -- gender unknown -- now has a temporary home with a library employee.
