Representative Matters

  • Commonwealth v. I-Dean F. – Court of Common Pleas, Philadelphia, PA – Total acquittal on Third Degree Murder and related weapons charges. Mr. Horowitz was retained as co-counsel to focus specifically on cell phone forensic and call detail record (CDR) data critical to the prosecution’s case. Mr. Horowitz’s focused cross-examination of the prosecution’s cell phone expert witnesses highlighted exculpatory information buried in thousands of pages of Call Detail Records and undermined the reliability of the prosecution’s cell phone forensic evidence.

    Through Mr. Horowitz’s meticulous analysis of call detail records and cell phone forensic data, his cross-examination at trial demonstrated that the Police Department’s failure to follow basic principles of forensic cell phone acquisition and analysis resulted in unreliable data, forcing a prosecution expert witness to admit on cross-examination that “the contents of the [text message database file] was modified sometime after the cell phone was taken into police custody.”

    The Jury acquitted on all counts, including Murder in the Third Degree.
