Overview
- Lake County prosecutors arrested Dr. Stephen Miller and charged him with three felony counts of possession of child pornography after investigators tied file‑sharing activity to an IP address linked to his home.
- Authorities say the probe began with illicit activity detected on a peer‑to‑peer network and that investigators used software and IP attribution to identify a suspect location.
- Officers executed a search warrant at a Highland Park house on Ridge Road, seized multiple electronic devices and used two K9 units to locate additional hard drives during the search.
- The seized devices are now being examined by the Illinois Attorney General’s digital forensics team as prosecutors prepare court proceedings and seek to file more charges.
- Northwestern confirmed Miller worked at its Laser and Electronics Design Core Facility but declined to comment on personnel matters, and prosecutors say the case could lead to additional arrests or charges as forensic work continues.
