In early 1972, Pamela flew north to stay with a friend in Sausalito, Calif., carrying with her Morrison`s satchel. She hailed a cab in San Francisco for the trip to Sausalito. During the 45-minute ride, she talked with the taxi driver, a good-looking Merchant Marine named Michael Vejraska, 23, and unloaded her problems. She and Vejraska soon began a love affair that would last six months. On the night before she moved in with Vejraska, she gave her new lover a box of Morrison`s writings, which she had removed from the satchel and placed in a 12- by 17-inch gray metal strongbox. A thin adhesive label near the handle read ''127 Fascination.'' On April 25, 1974, Pamela was found dead in her Hollywood apartment of a heroin overdose. Scattered throughout her apartment were photocopies of Morrison`s poems and journals. Her parents quietly took them home, and Vejraska, who had heard the news of her death over the radio, now found himself the caretaker of the rest of Morrison`s unpublished writings in San Francisco. Vejraska kept the strongbox 12 years. His only contact with the Coursons came less than a month after Pamela`s death, when he returned her VW bus, record collection and a box of Morrison`s photocopied poems and journals.
