On October 22nd 1969, the Oakland Police Department took a call at 2:00 am from somebody claiming to be the Zodiac Killer, requesting that either Melvin Belli or Francis Lee Bailey, high profile lawyers at the time, appear on a chat show hosted by Jim Dunbar later that day. Melvin Belli agreed to appear on the show, to which a man would eventually contact via telephone, claiming not only his name was 'Sam', but by inference that he was the infamous Zodiac Killer. The call was later attributed to hoaxer, Eric Weill, whose father's name just happened to be Sam.

The Palo Alto Times reported Patrol cars convoyed school buses around Palo Alto yesterday after a telephoned murder threat by a man claiming to be the Zodiac killer of five persons. The caller to the Palo Alto Times said he intended to "pick the kids off as they get on the school bus." The weird slayer, who signs himself "The Zodiac", made a similar threat in a letter to the San Francisco Chronicle last week after the Oct. 11 shooting of a taxi driver. Handwriting tests and descriptions of two victims who survived have convinced police that the same person. The district transportation supervisor said an armed guard might ride with each of the system's 25 buses. Officers in Napa and Vallejo, areas of the first three murderous attacks, some 75 miles north of Palo Alto, have been convoying police officers. Palo Alto Police Chief William Hydie called the new threat "extremely serious," but warned against over reaction to what might be a crank call.
We have two phone calls separated by one-and-a-half months, with both callers claiming they left the Bay Area because "because I'm too hot there" and "it got too hot for me". Either it's coincdence (and both are hoaxers), the second caller recalled the phrase used by the first caller one-and-a-half months earlier (and one caller may be Zodiac), or both phone calls were made by the Zodiac Killer, who was simply enjoying the terror he was inflicting on the people of northern California.
