Built on Investigation. Expanded by Technology.
IRIS began with a foundation in field investigation—developing witnesses, conducting surveillance, examining records, reconstructing events, and pursuing difficult leads.
As digital evidence became increasingly important to litigation, IRIS expanded its capabilities to include digital forensics, cellular and location evidence, evidence preservation, and advanced device recovery.
Today, these capabilities work together, allowing IRIS to develop and evaluate physical, documentary, testimonial, and digital evidence as part of the same investigation.

RIS brings together experienced investigators and digital-forensic specialists with expertise in complex investigations, forensic examination, advanced evidence recovery, and independent technical review.

Selected Investigative Experience
These selected matters illustrate the range of investigative work IRIS brings to complex cases and the impact that independent investigation and evidence review can have.
Anthony Christiana
Mike and the IRIS team were initially retained to examine Anthony Christiana’s current cell phone after he was charged with murder in connection with a 2015 Hartford shooting. When that device did not contain evidence addressing an eyewitness description of the gunman as clean-shaven, Mike went beyond the original scope and assessed what other evidence might exist, leading to the identification and recovery of Christiana’s previous phone.
A forensic examination of the older device recovered a photograph taken approximately 14 hours after the murder showing Christiana with a mustache and goatee, materially conflicting with the eyewitness description. The state ultimately dropped the murder charge.

Michael Skakel
Mike served as lead investigator in the post-conviction investigation of Michael Skakel.
His work included locating and developing Dennis Ossorio as an alibi witness, investigating third-party culpability, developing additional witnesses, and conducting geographic and timeline analysis.
Mike’s alibi investigation contributed directly to the habeas result that led to Skakel’s release on bail in 2013.

Vernon Horn
Mike’s work included substantial witness development, geographic and timeline reconstruction, and other investigative work that contributed to the broader post-conviction effort.
Later-discovered historical telephone records became important additional evidence in the cases that ultimately led to the release of Vernon Horn and Marquis Jackson.
The case became a turning point in Mike’s work. It led him to examine more broadly how historical cell-site and other digital evidence had been handled in post-conviction cases and ultimately contributed to his decision to establish the Digital Innocence Initiative.

Grant v. Commissioner of Correction
Mike investigated historical cell-phone records in Cecil Grant v. Commissioner of Correction, identifying discrepancies between the underlying records and testimony central to the prosecution’s theory.
His investigation and testimony were presented during the habeas proceedings. In January 2026, the Connecticut Supreme Court concluded that the previously unpresented cell-phone records could have significantly undermined key prosecution testimony and supported Grant’s defense.
The Court ordered Grant’s convictions vacated and a new trial.
