For Counsel

Co-Counsel & Expert Consulting

We partner with other attorneys on matters where technical evidence or a complex trial calls for additional depth, as co-counsel or as consulting experts, while you remain the client's primary counsel.

How we work with other firms

Co-counsel at trial

We join trial teams to handle technical witnesses, cross-examine the government's or an opponent's forensic experts, and present electronic evidence clearly to the jury.

Motion practice

Suppression motions, Daubert and Frye challenges, and other motions that turn on how electronic evidence was collected, preserved, and interpreted.

Case analysis and strategy

Early review of discovery, including phone extractions, cloud records, location data, and server logs, to identify the issues and shape the strategy.

Appeals and post-conviction

Briefing on issues involving technical evidence, in direct appeals and post-conviction proceedings.

Expert consulting

Forensic analysis of electronic evidence and help preparing to cross-examine opposing experts. Where a matter calls for it, Mr. Horowitz is also available to testify as an expert in computer and cell phone forensics.

Selected co-counsel matters

Estados Unidos contra Ulbricht (Silk Road)

Retained as co-counsel to analyze terabytes of forensic data. His declaration challenged the FBI's account of how it located the Silk Road server.

Commonwealth v. I-Dean F.

Retained as co-counsel to focus on cell phone forensics and call detail records. The jury acquitted on all counts, including third-degree murder.

United States v. D.S.

Together with co-counsel, obtained a non-jail sentence where the government sought 51 to 63 months' imprisonment.

Prior results do not guarantee a similar outcome.
