## Facts

- On March 3, 2013, law enforcement went to Todd David Linson’s home after receiving information that child pornography might be on a computer there.
- The computer was password protected. When Linson arrived, he provided the login password, allowing officers to view the web-browsing history.
- Officers observed searches and browsing history using terms associated with child pornography and visits to websites containing child pornography, and they seized the computer.
- A forensic examination found two user profiles on the computer.
- The examiner located forty-one images of possible child pornography in the browser cache associated with Linson’s user profile.
- The examiner also found an additional 360 images of child pornography in the computer’s unallocated space.
- The forensic review identified search terms such as “preteen,” “nude preteen photos,” “free preteen photos,” “no tits,” and “Lolita,” along with adult-pornography searches around the same time.
- On September 24, 2014, a grand jury indicted Linson on five counts of knowingly possessing child pornography under SDCL 22-24A-3(3), each count tied to a separate image found in the cache of Linson’s user profile.
- At the April 2016 jury trial, Linson moved for a judgment of acquittal before the case was submitted to the jury, arguing that cache files did not prove he knowingly possessed the images. The circuit court denied the motion.
- The jury found Linson guilty on all five counts, and the court imposed five-year penitentiary sentences on each count, to run consecutively.
- Linson appealed, challenging the sufficiency of the evidence and raising constitutional claims (vagueness and double jeopardy) that had not been raised in the circuit court.

## Issues

1. Whether the evidence was sufficient for a rational jury to find beyond a reasonable doubt that Linson knowingly possessed child pornography when the charged images were found in his browser cache.
2. Whether SDCL 22-24A-3(3) is unconstitutionally vague as applied to images stored in a browser cache (reviewed for plain error because not raised at trial).
3. Whether five convictions based on five separate cache images violated double-jeopardy protections as multiple punishments for a single act or course of conduct (reviewed for plain error because not raised at trial).

## Decision

- The Supreme Court of South Dakota affirmed Linson’s convictions and sentences.
- The court held that the State presented sufficient evidence for a rational jury to find knowing possession, including the placement of the images in the cache tied to Linson’s user profile and evidence of intentional, child-focused search terms and browsing.
- The court rejected Linson’s vagueness challenge on plain-error review, finding no plain error requiring relief regarding the constitutionality of SDCL 22-24A-3.
- The court rejected Linson’s double-jeopardy claim on plain-error review, finding no plain error in allowing five convictions tied to five distinct images.

## Legal Principles

- In reviewing a denial of a motion for judgment of acquittal based on sufficiency of the evidence, the court views the evidence in the light most favorable to the verdict and asks whether any rational trier of fact could find the essential elements beyond a reasonable doubt.
- Knowing possession of child pornography may be proven through circumstantial evidence, including computer-forensic evidence linking the images to the defendant’s user profile and evidence of intentional internet searching and viewing associated with the images.
- Unpreserved constitutional claims are reviewed only for plain error; relief requires an obvious error affecting substantial rights.
- When a defendant is charged with multiple counts tied to separate images, multiple convictions do not amount to a clear double-jeopardy violation on plain-error review absent an obvious showing that the counts punish the same offense.

## Conclusion

In South Dakota v. Linson, the South Dakota Supreme Court affirmed five convictions for knowingly possessing child pornography where the charged images were located in the browser cache associated with Linson’s user profile and were supported by evidence of intentional searches for child-related sexual content. Because Linson did not raise vagueness or double-jeopardy objections in the circuit court, the Supreme Court reviewed those claims only for plain error and found no obvious constitutional defect warranting reversal, leaving the consecutive sentences intact.
