On November 29, a carbon copy of a typewritten letter allegedly by her killer was mailed to Riverside PD and the Riverside Enterprise, claiming that he had killed her because of all the brush offs she had given him, but many of the details included in the appropriately titled “Confession” letter had already been published in the paper. A desk that was in the library annex the night Cheri Jo was murdered was discovered in storage in December 1966 with a poem etched into the top that was thought to be about her murder; it was the opinion of Sherwood Morrill, the state’s top Questioned Documents examiner for many years, that it was written by the Zodiac.

They were supposed to go to a Christmas concert that night at Hogan High (just a few blocks from Jensen’s home), but visited a friend named Sharon instead, then stopped at Mr Ed’s, a restaurant. Meanwhile on Lake Herman Road, a white Chevrolet was observed parked in a gravel turnout by two hunters, who approached it at one point, but the driver was nowhere to be seen.
The unsolved Zodiac murders are a bizarre and notorious California serial killer (Zodiac Killer) case which inspired one of the Dirty Harry movies. There have been many theories and suspects proposed about the Zodiac killer.

Maloney vociferously objected to the closing of the Zodiac case by his supervisor, Lieutenant John Hennessy. The Zodiac Killer:
