Guidance Software, developer and distributor of the computer forensic software Encase, is located in Pasadena, CA.

EnCase was the first product to search, recover, organize, and prevent changes to computer evidence, all within the convenience of a familiar Windows interface. EnCase was designed from the ground up to fit the specifications and requirements of law enforcement, and withstand legal challenges by preserving the integrity of computer evidence. The new EnCase Enterprise edition gives Corporate America the now familiar interface for secure investigations of servers and work stations inside a LAN/WAN.

EnCase has been used in hundreds of successful criminal prosecutions around the world, but perhaps most notably in the Jeremy Strohmeyer Rape/Murder case in Las Vegas, Nevada. In this case, over 700 deleted child-porn images were retrieved from the suspect's hard drive, and presented to defense counsel. The defendant subsequently pled guilty to Murder in the First Degree and was given a life sentence.

EnCase was also used in one of the first "cyber-stalking" cases to be prosecuted in the United States. A Los Angeles area man assumed the online identity of a woman, inviting strangers to her home. Evidence of his crime was found in "slack" areas of the hard drive that are inaccessible to most non-forensic software.

Currently Guidance Software has over 6000 users in the private sector and local, state and federal law enforcement agencies worldwide. The Encase training staff has trained hundreds of investigators and auditors across the country on EnCase and its unique case-based methodology. There are now 3 full time training facilities in Southern California, Northern Virginia, and the United Kingdom.

The EnCase training staff members are law enforcement professionals, involved in conducting computer forensic examinations in criminal investigations. Bill was a Special Agent with the United States Customs Service, Office of Investigations for 21 years and taught as a member of the EnCase training staff during 1999 and 2000. During that period, he conducted numerous investigations of narcotics smuggling, money laundering, child pornography distributions, and other violations of the United States Code. He conducted computer forensic examinations from 1992 – 2000, in support of the criminal investigations conducted by the SAIC office in Los Angeles, CA.

Bill is a member of the International Association of Computer Investigative Specialist (IACIS) and the High Technology Crime Investigation Association (HTCIA). He has received formal training on computer evidence recovery and the science of computer forensics from IACIS, HTCIA, and the National Consortium for Justice Information and Statistics (SEARCH). He has successfully completed the four-week Basic Seized Computer and Evidence Recovery School (SCERS) at the Federal Law Enforcement Training Center (FLETC) in Glynco, GA and the three-week Advanced Seized Computer and Evidence Recovery School (ASCERS) at the Customs Cybersmuggling Center (C3) in Fairfax, VA.

Bill has also provided formalized training to other Federal Agents, State, and local police officials on the U.S. Attorneys Guidelines for Searching and Seizing Computers and the best methods for presenting computer evidence in trial. He has testified in federal court on computer issues, as they relate to the proper procedures for processing computer evidence.

He has received formal Novell network computer training and was also the Novell Network Administrator for the SAIC/Los Angeles local area network.
