I wanted to thank you for all your help with the case. Your expertise was amazing. You have such a gift. Many lawyers have asked me who I used as an expert because they knew I had a big cell tower forensic case. I will be sending word to our legal community that they should use you as an expert.

Snapchat and Murder
Meticulous analysis reveals critical cellphone evidence
A member of a notorious gang was found murdered in a small California city. Police had arrested a known associate of the gang (the Suspect) on grounds that cell phone towers showed his location at the crime scene during the given time window. The Suspect claimed that he did not commit the murder, but was at the crime scene. He identified another individual (the Defendant) as the murderer. The Defendant denied being at the crime scene, and denied being with the Suspect at any point during the day that the crime was admitted. The Defendant’s attorney hired ArcherHall to look through his cell phone for evidence pertaining to the crime.

Malpractice at a Surgical Facility
Forensic examination of Electronic Medical Records
Our client was the plaintiff in a case seeking to prove that a surgical facility was not following proper medical protocol and performing surgeries without the proper pre-surgery health assessment. Allegations were made that the facility was falsifying medical records by overwriting the pre-surgery assessment digital signatures with the post-surgery medical record signature. In effect, this data replacement was erasing the evidence of the malpractice.

Explicit Content in School
An innocent teacher is exonerated
We were retained to investigate accusations that a special education teacher had been browsing the internet for adult content, including suspected child pornography. The school’s web traffic monitoring software had flagged a site the teacher had visited. Given the severity of the accusations, the school executives wanted to verify with certainty that the allegations were accurate.
From the Attorney: “I wanted you to know how much the [client] and I appreciated the work done by you and your team to resolve the mystery involving [the teacher]’s computer. The fact that you didn’t simply accept the easy explanation — that he must have searched for pornography and hid it so well that you couldn’t find it — and doggedly pursued the truth, avoided what might have been a serious miscarriage of justice that could have resulted in [the teacher] losing his job, his reputation and maybe his freedom. You should also know that being under this cloud of suspicion has overwhelmed [the teacher] and, while he will take some time to recover, he is extremely relieved to have been exonerated. And the professionalism and expertise of you and your co-workers relieved [client] of the horrible burden of mistakenly taking action against an innocent man.”
