Cyber Forensic Expert in 2,000+ Cases Faces FBI Probe

A high-profile Minnesota digital forensics expert, Mark Lanterman of Computer Forensic Services, is under FBI inquiry and legal scrutiny for alleged misrepresentation of his education and employment history, with Perkins Coie and others unable to verify claimed Upsala College degrees and noting his “Harvard” credential was an online HarvardX course. Additional allegations include removing/withholding a police personnel file and threatening to auction client data in billing disputes, leading prosecutors and courts to reassess cases where he testified—potentially affecting prominent matters like the Stephen Allwine conviction, which has now petitioned for review.
