Stalking Investigations in South Dakota

01Safety first

Your Safety Comes Before Any Investigation

If you feel unsafe right now, call 911 or the local police or sheriff. An investigator is not a bodyguard and cannot stop someone in the moment. Law enforcement can respond, take a report and, in many cases, act on what they see. Keep your phone charged, tell someone you trust about the situation, and vary routines where you can. If the person stalking you is a current or former partner, local domestic violence programs can help with safety planning, and counsel can explain your options.

Our work begins once you are safe enough to plan. We help you turn scattered incidents into a clear, dated record, check your vehicle and home for tracking devices or hidden cameras, and, where useful, document the stalker's conduct from public places. Everything we gather is written for police, prosecutors and the court. Our surveillance investigations follow the same rules, and our guide to lawful investigator activity explains the limits we observe.

02The statute

How South Dakota Defines and Grades Stalking

South Dakota's stalking law, SDCL 22-19A-1, covers three kinds of conduct: willfully, maliciously and repeatedly following or harassing another person; making a credible threat with intent to place someone in reasonable fear of death or great bodily injury; and willfully, maliciously and repeatedly harassing someone by verbal, electronic, digital media, mechanical, telegraphic or written communication. That last clause reaches texts, social media, email and calls. Our cyberbullying investigations address online harassment specifically.

A first conviction is generally a Class 1 misdemeanor. A second or later conviction within ten years is generally a Class 6 felony, and convictions from other states count toward that history. Related statutes may also apply: SDCL 49-31-31 makes threatening or harassing electronic contact, repeated anonymous calls and spoofed caller ID a Class 1 misdemeanor. Workers harassed by a coworker may also have workplace remedies, covered on our workplace harassment page. The charging decision belongs to the state's attorney, and our investigations for attorneys support victims' counsel in presenting the facts.

03Court protection

Protection Orders and the Evidence Courts Look For

Under SDCL 22-19A-8, a person may petition for a protection order alleging stalking, physical injury from an assault, or a crime of violence. The petition must be supported by a sworn affidavit of specific facts, and the clerk of the circuit court provides forms prepared by the Attorney General. Magistrate courts share jurisdiction over stalking protection orders. Where the stalker is a family or household member, the domestic abuse process in SDCL chapter 25-10 may also apply, with relief for a fixed period of up to five years. Counsel can explain which path fits, and our specialized investigations team supports either one.

Specific facts are what make a petition strong. Judges want dates, times, places, what was said or done, and how it affected you. We help organize that into a chronology with supporting screenshots, photographs and witness statements. Once a petition is filed or an order issued, it must be served, and our process serving in South Dakota handles that with logged, time-stamped attempts and a signed affidavit. Our guide to serving legal papers explains the general rules.

04Building the record

Documenting a Pattern of Following and Contact

Stalking is a pattern, so the record must show repetition. We start with a log of every incident you remember, then attach whatever proof exists: screenshots with usernames and timestamps, call logs, photos of the person or vehicle, and names of anyone who saw it. Where the person keeps appearing at your work, gym or church, an investigator can observe and photograph from public places to confirm the pattern independently. That independent view often carries weight with officers and judges. Our Sioux Falls investigators handle many of these cases.

Recording rules matter. SDCL 23A-35A-20 generally allows a participant in a conversation, or someone with a participant's consent, to record it, so you may lawfully record a call the stalker makes to you. Recording other people's private conversations without consent is a crime. Our recording law guide explains the details. If the stalker is someone you dated, a dating background check can show prior orders or cases. We also never contact the stalker, which could escalate the situation and complicate the case.

• Date, time and place of every incident
• Screenshots showing usernames and timestamps
• Photos of the person or vehicle, if safe
• Names of anyone who witnessed an incident
• How each incident affected you

05Tracking and cameras

Checking for GPS Trackers, Hidden Cameras and Account Access

Stalkers often seem to know where a person is. Sometimes that comes from a GPS tracker hidden on a vehicle, a shared phone location setting, a compromised account, or a hidden camera. We inspect vehicles and homes for physical devices and help you review phone and account settings you control. South Dakota has no specific GPS-tracker statute that we have verified, but covert tracking can support stalking, harassment and trespass claims, and we document any device we find for police without destroying evidence. Travelers worried about rooms and rentals can also ask about our hotel and rental surveillance checks.

Hidden cameras are addressed directly by state law. SDCL 22-21-1 makes it a Class 1 misdemeanor to install or use a device in a private place to observe or record without the consent of those entitled to privacy, and SDCL 22-21-4 covers recording or distributing intimate images without consent, with a 2026 amendment addressing digitally fabricated images. If we find a device, we photograph it in place and advise you to involve police before removing it. To reduce what strangers can find about you, see our personal information and OSINT wipe.

06Unknown harasser

When You Do Not Know Who Is Behind It

Some stalking comes from fake accounts, blocked numbers or anonymous letters. Identifying the person can be hard, and platforms and phone carriers generally release subscriber information only to law enforcement or through legal process. What we can do is analyze patterns: writing style, timing, details only certain people would know, and public information tied to the accounts. That analysis gives police and counsel a starting point for subpoenas or warrants. Our skip tracing in South Dakota tools help once a likely name emerges.

Spoofed caller ID is common in these cases. SDCL 49-31-31 prohibits using spoofed caller ID to defraud or to display another person's number without permission, and repeated anonymous calls are also covered. Keep every voicemail and call log. When a likely suspect is identified, a witness background check on that person can help counsel assess risk and history before the next step, always within lawful public sources.

07South Dakota realities

Stalking in Small Towns, College Towns and Across State Lines

In small South Dakota communities, the person stalking you may share your grocery store, church and kids' school, which makes avoidance hard and witnesses awkward. In college towns like Brookings, Vermillion, Aberdeen and Spearfish, stalking can follow students between campus, work and apartments. Either way, local patterns matter. We plan observation around those realities and coordinate through our Brookings investigators and Vermillion coverage for campus-area cases.

Stalkers sometimes cross borders. A person may drive from Sioux City into Union County, or from Wyoming into the Black Hills. South Dakota's stalking law counts prior out-of-state convictions, and protection orders from other states can be enforced under federal law. On reservation land, tribal courts and police may have jurisdiction, and counsel should advise on the right forum.
