Karl Francis Warner (born 1950) is an American serial killer. He was active in Santa Clara County, at the southern end of the San Francisco Bay Area, in Northern California. He was convicted of the murder of three teenaged girls during his period of activity from 1969-1971. On August 3, 1969, the bodies of Deborah Gay Furlong, 14, and Kathy Snoozy, 15, were found on a hillside in San Jose's southern Almaden Valley. According to Santa Clara County Medical Examiner Dr. John E. Hauser, the girls died in a 'frenzied flurry of knife wounds,' totaling nearly 300. On Sunday, April 11, 1971, Kathy Bilek, 18, visited Villa Montalvo, in Saratoga, with the intent to read and engage in birdwatching in the seclusion of a remote, wooded portion of the park, near a small stream. Her body was found the next day by her father, Charles, while Santa Clara County Sheriff's deputies searched nearby. She'd been stabbed 49 times. Bilek was murdered in the Villa Montalvo park in Saratoga.
