Untitled Document

Saturday, October 24
8:00 - 9:15am

Digital evidence is hard to navigate and handle without first understanding the basics. The presenters will teach the audience the basics of digital evidence, forensic images and the correct terminology and concepts. Discussion will focus on the technical differences between a physical forensic image and a logical evidence file, and also on the benefits of one over the other in certain circumstances.  Also covered will be what makes a forensic image “forensic” and why it is defensible from both a technical and legal view. After the basics are covered, the presenters will walk the audience through more advanced issues dealing with issues to include iPhones, Gmail and some of the most favored media sites. 

Speakers: Benjamin Rose, David Townsend, Townsend, Carden & Rose, Inc.; and Lisa Sherman, Sherman Law Group

Lisa Sherman

Lisa Sherman

Lisa Sherman is the President of Sherman Law Corporation where she practices employment law exclusively. Her practice consists of litigation, advice and counsel, training and conducting independent employee investigations. On November 28, 2014, the Daily Journal’s Solo and Small Firms Section featured Sherman Law Corporation, following the voluntary dismissal of two simultaneous lawsuits alleging wrongful termination and a wage and hour class action where her client employer paid no money after less than six months of litigation.

Ms. Sherman graduated from the University of Rochester in 1990 double majoring in Economics and Political Science. Surrounded by a family full of physicians and deathly afraid by the sight of blood, she took refuge in law school. Lured by the prospect of being paid to argue, she journeyed west, graduating in 1993 from Washington University School of Law in St. Louis, Missouri, where she was awarded an American Jurisprudence Award in Trial Advocacy. She remains active promoting the law school, helping new graduates, and actively participating in the William Greenleaf Eliot Society.

Ms. Sherman has practiced labor and employment law ever since graduation, having built her foundation training at the nation’s largest and best-known labor and employment firm, Littler Mendelson, at two highly prestigious boutique law firms Knee & Ross, LLP, in Los Angeles, California, and Kamer & Ricciardi, in Las Vegas, Nevada. She also served as (the only) in-house counsel for a nurse registry company with six offices overseeing several thousand employees. In addition, she has authored a number of articles in labor and employment law which have appeared in notable publications such as, The Labor Lawyer and The Employment & Labor Relations Law of the American Bar Association Section of Litigation, Spring 2015 edition. Most recently, she co-authored an article that will be featured in, entitled, "E-Discovery Competency- Beyond the Rules" with her co-presenters, Benjamin Rose and Jim Carden, digital forensic experts, with whom she is collaborating on various other projects to advise companies, in-house and outside counsel, as well as, investigators on best practices in connection with the collection and preservation of admissible digital evidence in the workplace.

Aside from her busy law practice, raising two teenage girls (ages 16 and 14), and living the life of a weekend sports widow, she is also a member of various professional associations, although none has had a greater impact on her practice than the Association of Workplace Investigators, which she was introduced to by AWI member Lynne Davis. Ms. Sherman completed AWI's training institute in February 2015 which she strongly recommends. Significantly, if it were not for the AWI Training Institute, she never would have met Jim Carden, whose presentation on digital evidence was the first one of its kind she ever understood. [She later learned that Jim's secret weapon was our very own, Alexander Sperry, who impressively prepared a jet-lagged Jim who arrived hours before their 8 am presentation from "remote imaging computers" in Greece.] Ms. Sherman currently co-chairs the newly revived West Los Angeles AWI Section with fellow AWI members, Lynne Davis and Allison Underwood.
