Investigation
In January 1987, a convention for arson investigators from California was held in the city of Fresno. During and after the convention, several suspicious fires were set in Bakersfield. This, combined with the recovery of a single unmatched fingerprint left on a piece of notebook paper as part of a time-delay incendiary device, led Captain Marvin G. Casey of the Bakersfield Fire Department (BFD) to suspect that an arson investigator from the Los Angeles area was responsible for these arsons.
During March 1989, another series of arsons was committed along the California coast in close conjunction with a conference of arson investigators in Pacific Grove, California. By comparing the list of attendees from the Fresno conference with the list of attendees at the Pacific Grove conference, Captain Casey of the BFD was able to create a short list of ten suspects. Orr was on Casey's short list, but all of the people on this short list were cleared of suspicion when their fingerprints were compared with the fingerprint that Casey had recovered from the piece of notebook paper found at one of the arson crime scenes.
In late 1990 and early 1991, another series of arson fires broke out in southern California, this time in and around the Los Angeles metropolitan area. As a result, a large task force, nicknamed the Pillow Pyro Task Force (a reference to the arson fires set in pillows) was formed to apprehend the arsonist. On March 29, 1991, Tom Campuzanno of the Los Angeles Arson Task Force circulated a flier at a meeting of the Fire Investigators Regional Strike Team (FIRST), an organization formed by a group of smaller cities in and around Los Angeles County that did not have their own staff of arson investigators. The flier described the modus operandi of the suspected serial arsonist in the Los Angeles area. Scott Baker of the California State Fire Marshal's Office was at that meeting and told Campuzanno about the series of arsons investigated by Captain Casey of the BFD and about Casey's suspicions that the perpetrator was an arson investigator from the Los Angeles area. Consequently, Campuzanno and two of his colleagues met with Casey, obtained a copy of the fingerprint that Casey had recovered, and matched it to John Leonard Orr on April 17, 1991.
Orr then became a serious arson suspect and the subject of investigation and surveillance for several months. Orr was alerted to this surveillance effort on May 3, 1991, when he discovered and removed a tracking device that belonged to the Bureau of Alcohol, Tobacco, and Firearms (ATF) hidden under the bumper of the vehicle he was driving. However, Orr was apparently unaware of the fact that a Teletrac tracking device was later installed behind his dashboard when he brought his city vehicle for service on November 22, 1991. Meanwhile, a federal grand jury handed down an indictment, and shortly thereafter Orr was present at the scene of a suspicious fire, so a decision was made to end the surveillance, obtain an arrest warrant, and effect an arrest. Orr was arrested on December 4, 1991.
