Recent Cases 
· subsequent to the Court's digital evidence
discovery order, an forensic examination determined that a Defendant
intentionally deleted relevant data using a "shredder" program.
Evidence of the search for, download of and use of this shredder
program was presented in court along with expert testimony. Defendant
received monetary sanctions and precluded from testifying at trial.
· an HR department suspected a key employee was
stealing company documents and preparing to delivery them to his new
employer. The employee's company laptop was seized and zip files
containing sensitive files were recovered.
· a company defending a sexual harassment suit
requested the examination of their accuser's and manager's PCs. An
examination revealed the specific allegations of images on the
manager's PC were in fact there and nothing was found on the accuser's
PC. An immediate settlement was negotiated.
· an accounting manager for a pharmaceutical
manufacturer used his employer's funds to pay off a personal loan. Mr.
McLaughlin recovered evidence of the fraud and cover-up through his
forensic computer search, and then interviewed the subject who
confessed to the fraud. A referral was made to local law enforcement
and our client received partial restitution.
· planned and managed a tactical operation for a
major electronics company to seize digital evidence pertaining to an
international computer peripherals piracy scheme. Mr. McLaughlin
conducted an exhaustive bit-by-bit analysis of the computer hard
drives, running the Chinese version of Windows, then reconstructed the
conspiracy, including the recovery of "deleted" emails and financial
records.
· a marketing manager conspired to submit
fraudulent invoices totaling $300,000 to his employer. Mr. McLaughlin
recovered evidence of the complex fraud scheme from erased document and
fax data files and email messages, then referred this matter to local
law enforcement for prosecution.
· working under a court order for the review of
computer evidence in a major entertainment industry civil case, Mr.
McLaughlin conducted an analysis of the company's server network,
recovered key information critical to the plaintiff in the case.
Additionally, Mr. McLaughlin uncovered digitally "embedded" information
confirming the defendant used a "sanitizing utility" on many of the
files less than four hours prior to his court ordered review,
potentially destroying evidence. He testified as an expert witness and
the defendant was sanctioned $120,000 for spoilage of evidence and the
plaintiff ultimately won a $4 million judgment.
· an insurance company potentially liable for a
$300,000 entertainment claim, needed to determine if internal

searched for evidence. It was determined that only employee negligence
contributed to the claim.
