Computer forensics is the collection, preservation, analysis, and presentation of computer-related evidence. Computer evidence can be valuable in criminal cases, civil disputes, and human resources/employment proceedings.

Far more information is retained on a computer than most people realize. It's also more difficult to completely remove information than is generally thought. For these reasons (and many more), computer forensics can often find evidence of, or even completely recover, lost or deleted information, even if it was intentionally deleted.
​
Berryhill Computer Forensics has a proven track record of excellence in computer forensics — electronic evidence recovery, analysis and expert witness testimony.

We assist with both civil and criminal proceedings for:
  • Attorneys
  • Investigators
  • Litigation support firms
  • Law enforcement
  • Government agencies
  • Corporate security / human resources

In many cases, the computer forensic evidence we discover provides the crucial evidence needed for a successful outcome. Often, solid computer evidence is instrumental in bringing about a swift conclusion to a case. We have analyzed more than 10,500 pieces of electronic media in over 1,250 cases. Many cases settle out of court once the computer evidence is presented. When a case does go to trial, we are unmatched in our skill and experience at presenting computer evidence in clear terms to judges and juries.

​Our principal, Jon Berryhill has been certified to testify as an expert in: 
  • Military courts
  • State courts
  • Federal courts
He has testified in court 57 times and been deposed as an expert 36 times.
