## Facts

- A computer-repair technician, while servicing Justin Hill’s computer, saw images she believed were child pornography and reported her observations to police.
- A detective obtained a state search warrant authorizing a search of the repair store and seizure of the computer, related records, and computer storage media associated with Hill, as well as sexually explicit images depicting minors contained in that media.
- When officers went to the repair store to execute the warrant, Hill had already retrieved his computer.
- Officers then searched Hill’s home and seized various computer storage media (but did not locate the computer itself).
- Police transported the seized media to a police laboratory and conducted a forensic examination off-site, which revealed child pornography.
- In federal court, Hill moved to suppress the evidence, arguing the warrant was overbroad and the seizure of all media for an off-site search was unreasonable because the search should have been performed on-site to limit access to nonresponsive files.
- The district court denied suppression. Hill entered a conditional guilty plea to possession of child pornography, preserving his right to appeal the suppression ruling.
- Hill appealed to the United States Court of Appeals for the Ninth Circuit.

## Issues

1. Whether the search warrant, supported by the technician’s description of the images, established probable cause to search for child pornography on Hill’s computer-related storage media.
2. Whether the warrant satisfied the Fourth Amendment’s particularity requirement when it authorized seizure of Hill’s computer storage media and a later search for sexually explicit images depicting minors.
3. Whether it was reasonable under the Fourth Amendment for officers to seize the storage media from Hill’s home and conduct an off-site forensic examination in a laboratory rather than limiting the search to an on-site review.

## Decision

- The Ninth Circuit affirmed the district court’s denial of the motion to suppress and left Hill’s conditional guilty plea and conviction in place.
- The court held there was probable cause to search for child pornography based on the technician’s account of what she saw, which supported a fair probability that illegal images would be found on the relevant media.
- The court concluded the warrant’s description of the items to be seized and searched was sufficiently specific in light of the suspected offense and the nature of computer storage.
- Although the court identified overbreadth concerns with authorizing seizure of all computer-related property for later examination without a detailed showing of need, it held suppression was not warranted on this record because the search and seizure were reasonable in execution and driven by practical limits of computer forensics, not a general rummaging for unrelated evidence.

## Legal Principles

- The Fourth Amendment requires that warrants be supported by probable cause and describe with reasonable specificity the places to be searched and the items to be seized.
- Probable cause may be supported by a witness’s specific description of observed images and surrounding facts showing a fair probability that contraband or evidence of a crime will be found.
- A warrant’s particularity is assessed in a practical way, taking account of the nature of the evidence sought and the context supplied by the supporting affidavit.
- Digital searches present special problems because responsive files may be intermingled with large amounts of unrelated data; a warrant may permit seizure or copying of storage media for later review when that method is a reasonable way to locate the items described.
- Even when a warrant is broader than necessary in some respect, suppression is not automatic; courts consider whether the search was carried out in a reasonable manner and whether officers acted to find the evidence described, rather than to conduct a general exploratory search.
- A defendant who enters a conditional guilty plea may preserve appellate review of a denied suppression motion.

## Conclusion

United States v. Hill affirmed the denial of suppression where police, acting on a technician’s report of suspected child pornography, obtained a warrant, seized computer storage media from Hill’s home, and conducted an off-site forensic search that uncovered illegal images; the Ninth Circuit held the warrant was adequately supported and described, and that the manner of executing the search was reasonable under the Fourth Amendment.
