description was broadcast on the police radio, a "docile" Mullin was ordered to pull over and was arrested by a patrolman. In his car was the .22 caliber pistol used to kill the people in the cabins. He did not attempt to use the recently fired .22 caliber rifle on the seat next to him. The police failed to recognize a pattern at the time of Mullin's murders due to several factors: firstly, the murders did not appear to be connected by a similar weapon or modus operandi; secondly, the victims differed from each other in terms of age, race, and sex; and finally, Edmund Kemper, who would kill the last of his own eight victims just a few weeks later, was operating in approximately the same area at the same time. Mullin had committed his murder spree over four months. Trial and imprisonment The Santa Cruz County District Attorney's office charged Mullin with ten murders, and Mullin's trial opened on July 30, 1973. Mullin had admitted to all the crimes and therefore the trial focused on whether he was legally sane (which, under U.S law, means that he understood the nature and quality of his actions, and understood right from wrong). The fact that he had covered his tracks and shown premeditation in some of his crimes was highlighted by prosecutor Chris Cottle, while the defense (public defender Jim Jackson) argued that Mullin's delusions made him kill. On August 19, 1973, after fourteen hours of deliberation, Mullin was found guilty of first-degree murder in the killings of Jim Gianera and Kathy Francis because they were deemed premeditated and eight counts of second degree murder in the other killings because they were considered "impulse" by the jury. Mullin was convicted of the ten murders at the age of 26. The Santa Clara County District Attorney's office charged Mullin for the murder of Henri Tomei. On December 11, 1973, the day his trial was to begin, he pleaded guilty to second-degree murder after originally pleading not guilty by reason of insanity to first-degree murder. He was sentenced to life imprisonment in the Santa Cruz County trial and was denied parole eight times from 1980 on. He was incarcerated at Mule Creek State Prison, in Ione, California. While in custody, Mullin said he committed his crimes only in an attempt to save the environment. He was diagnosed by Dr. David Marlowe from
