Monday, March 22, 1971 A postcard arrived at the Chronicle covered with newspaper cutouts of pictures and phrases. The phrases "Sought victim 12," "peek through the pines," "pass LAKE TAHOE areas," "Sierra Club" and "around in the snow" had been cut from newspapers and glued down. Pasted to the back of the card was an artist's rendering of what was later discovered to be an ad for Forrest Pines, a condo village currently under development near Incline Village on the north shore of Lake Tahoe, Nevada. This card implied that Zodiac had claimed a twelfth victim, who may have been Donna Lass, a 25-year-old nurse who had been missing since Sept. 6, 1970, after she left work at the Sahara Hotel in Stateline, Nevada. The casino nurse's car was found parked near her small apartment, but there was no sign of any struggle and only her purse and the clothes she was wearing were missing. An unidentified male caller had told Donna's landlord and employer on the day she vanished that she would not be returning because of an illness in her family. The call proved to be a lie as there was no illness in the family. A formal search for Donna Lass was never conducted because of heavy snow. She has never been found.
