Someone Watching You? Act Now
Hidden cameras, tapped phones, and stalkers aren’t just unsettling—they’re dangerous. Our Chicago-based experts find and stop surveillance quickly, protecting your safety and peace of mind. Every investigation is confidential.
What Is Stalking?
Stalking is defined as someone repeatedly following, contacting, or monitoring another person without their consent or in a way that causes them fear or distress.
It can include unwanted phone calls, texts, emails, messages on social media, showing up at their workplace or home, and other forms of surveillance or harassment.
Stalking is often a criminal offense and can have serious consequences for both the stalkers and the victims. It is a violation of personal boundaries and can cause significant emotional and psychological harm to the victim.
Online stalking or cyber-stalking is another form of the offense, but this situation is more manageable. Users can update their privacy settings to avoid such behavior. Nevertheless, online stalking can turn into physical stalking, which is a significant escalation to be mindful of.

How Can You Identify a Stalker?
Recognizing stalking behavior early is key to protecting yourself. Look for patterns—not just isolated incidents.
Repeated unwanted contact
Frequent calls, messages, emails, or DMs despite no response or clear rejection. This behavior often intensifies over time, especially if the person believes they want a relationship with you.
Showing up uninvited
Appearing at your home, workplace, gym, or regular hangouts without permission. If you notice the same person parked outside your home or office repeatedly, take it seriously; this is no longer coincidence.
Monitoring your movements
Knowing where you are, who you’re with, or what you’re doing without you telling them. This level of awareness often means they’re gathering information about you online — checking your social media, tracking your check-ins, or asking people in your life behind your back.
Following or tracking you
Physically trailing you or using GPS, apps, or social media to keep tabs on you. In some cases, a stalker may get inside the car or place a hidden GPS tracker underneath it, something our digital forensics team can detect and document. If you suspect your vehicle is being monitored, a dashcam set to record continuously can also serve as critical evidence in case they get closer.
Obsessive online behavior
Liking, commenting, or reacting to everything you post—or creating fake accounts to watch you. This type of behavior signals that the person is fixated on you and could watch your movements and activity around the clock.
Unwanted gifts or messages
Sending items, notes, or deliveries after being told to stop. Don’t engage with any of it, even returning a package or sending a polite refusal signals that their behavior is getting a response.
Contacting people around you
Reaching out to your friends, family, or coworkers to gather information about you. This is a sign that the stalker is building a profile; they may not know what his motives are yet, but they’re clearly trying to get closer.
Threats or intimidation
Subtle or direct threats, manipulation, or attempts to scare or control you. Whether it’s a veiled comment, a car alarm going off at strange hours, or someone making you feel paranoid about your surroundings, these tactics are deliberate.
Ignoring boundaries
Continuing behavior after you’ve clearly said “no” or asked for no contact. Someone who repeatedly ignores your boundaries, especially someone you know, like a former partner or coworker, may have a history of violence or controlling behavior that a background check can reveal.
Escalating intensity
Behavior becomes more frequent, intrusive, or aggressive over time. This escalation is one of the clearest signals that it’s time to call the police and start building a formal safety plan with professional help.
What is stalkerware and how do you deal with it?
Stalkerware is a type of hidden software installed on a device to secretly monitor someone’s location, messages, and activity without their consent.
Types of Stalkers
Understanding what motivates a stalker can help you anticipate their behavior and assess your level of danger. Researchers have identified five primary stalker profiles:
The Rejected Stalker
Often a former intimate partner or close friend who cannot accept the end of a relationship. Their behavior typically alternates between attempts to reconcile and expressions of anger when those attempts fail. If this describes your situation, our infidelity and domestic investigations team has extensive experience with cases that begin in a relationship context and escalate after separation.
The Resentful Stalker
Motivated by a perceived grievance rather than a desire for a relationship. They want to frighten or cause distress as a form of retaliation, and they often see themselves as the real victim.
The Predatory Stalker
The most dangerous type. Their behavior is calculated and deliberate, motivated by power and control. They frequently plan their harassment in detail and may not make contact until they are ready to act.
The Intimacy-Seeking Stalker
Driven by a delusional belief that a romantic relationship either exists or is destined to develop. They often interpret any response, even rejection, as a sign of interest.
The Incompetent Suitor
Typically lacks social skills and pursues someone despite clear signals of disinterest, genuinely not understanding that their behavior is unwelcome or harmful.
Knowing which type you’re dealing with matters — not to excuse the behavior, but because the escalation risk, the appropriate response, and the legal strategy can differ significantly. This is part of the threat assessment a licensed investigator can help you work through. Contact our team to discuss your specific situation.
How to Catch Stalkers: Best Ways to Protect Yourself
Stalkers can be stubborn, and the victim might try to ignore them, hoping their indifference might stop the distressing behavior. However, ignoring the stalker often proves to be an ineffective method if they have no issues with crossing your boundaries.
Be Aware of Your Surroundings
If you have a stalker or suspect someone is violating your privacy, stay alert. Observe your neighborhood to check for any strangers or vehicles that pass frequently. Write down any suspicious events that would compromise your safety.
Also, don’t forget that social media makes it easier for stalkers to reach their target. A stalker can find your phone number, address, or email through social media and continue to harass you. Therefore, it is essential to conceal any private information online to limit their access.
Don’t Interact with the Stalker
As we’ve already explained, the stalker believes they have a relationship with their target. Any attempt to communicate with them directly can be perceived as validation. Never talk to them in person or answer their phone calls. Also, make sure not to respond to their text messages.
You should avoid any action that would signal interest to them. You might get frustrated and feel the need to yell at them, but even this action can be perceived as expressing interest.
Ask for Support
It might be best to share your concerns with someone you trust. Let your parents, spouse, neighbors, doorman, or coworkers know you’ve been harassed. Besides helping you in unpleasant situations, they can also spot the person and be a witness.
Call the Local Police Department
Even non-violent forms of stalking need to be reported to the police. However, remember they need at least two unwanted contacts to charge someone.
Get a Restraining Order
Severe cases of stalking require legal action, especially if the stalker has a history of violent behavior. The law can impose an order that requires the stalker to stay away from you.
Keep in mind, however, that getting a restraining order may escalate the violence. If there is a risk of violence, stalking victims can decide to find a new place to live. In such cases, they should take all the necessary measures to prevent the stalker from finding them. Remaining anonymous in public real estate records is a good way to enhance privacy and safety.
What are stalkers weak to?
Stalkers often rely on secrecy, control, and intimidation, so they’re weakest when their behavior is documented, exposed, and taken seriously by authorities or support networks.
What to Do if You’re Being Stalked Digitally
Online stalking can be just as threatening as in-person harassment. Today, with the technological advances we’re witnessing, it’s becoming more common than ever before.
Acting quickly and methodically helps protect your privacy and safety. If you suspect that you’re the victim of cyber stalking, consider doing the following:
Do not engage
Ignore messages, friend requests, or comments from the stalker — any response can escalate contact. Even a message telling them to stop can be interpreted as an opening, reinforcing the idea that persistence gets results. The safest approach is complete silence combined with active documentation. Let the evidence speak while you say nothing.
Tighten privacy settings
Make all social media accounts private, remove location tags, and limit who can see posts. Go through every platform you use, not just the ones you’re most active on, because stalkers often monitor dormant accounts looking for clues. Pay particular attention to older posts that may still contain your address, workplace, school, or daily routine.
Change passwords and enable 2FA
Use strong, unique passwords for every account and turn on two-factor authentication. If a stalker has had physical access to your devices at any point, assume your passwords may already be compromised and change them from a secure, unfamiliar device. A password manager can help you generate and store complex credentials without the risk of reusing anything the stalker might already know.
Block and report
Block the stalker on all platforms and report abusive behavior to the platform. Most major platforms have dedicated harassment reporting tools that can result in account suspension — use them, because each report creates a record of the stalker’s behavior. Keep screenshots of the accounts before blocking, as that documentation may be needed if you pursue legal action.
How can I document stalking incidents and collect evidence?
Keep a detailed log of every incident (dates, times, locations, what happened, and any witnesses), and save all evidence such as messages, emails, call logs, photos, and screenshots in a secure place.
Limit shared personal information
Avoid posting addresses, routines, travel plans, or personal photos publicly. This includes indirect clues: a photo taken outside your home, a gym check-in, or a tagged location at a restaurant you visit regularly can all give a stalker exactly what they need. Audit your past posts as well, since information you shared months or years ago may still be visible and actively being used against you.
Check for spyware or tracking apps
Scan devices for malware, keyloggers, or apps that might be tracking your location. These programs are designed to be invisible to the user, so a standard scroll through your installed apps is rarely enough to detect them. A professional digital forensics examination is the most reliable way to find and safely remove stalkerware without alerting the person who installed it.
Use secure communication tools
Consider encrypted messaging apps for sensitive conversations. Apps like Signal offer end-to-end encryption that prevents messages from being intercepted, even if someone is monitoring your network. If you’re coordinating with law enforcement, an attorney, or a private investigator about your case, conducting those conversations through an encrypted channel adds an important layer of protection.
Seek professional help if needed
Contact authorities or a digital safety expert if harassment persists. Law enforcement has increasingly specialized units for cyberstalking cases, and a licensed private investigator with digital forensics expertise can help identify anonymous accounts, trace IP addresses, and build an evidence file that meets the legal standards required to prosecute. The sooner you bring in professional support, the stronger your case will be.
How Can a Private Investigator Help?
Knowing you have a stalker is one thing. Proving it, in a way that holds up in court, is another. That’s where a licensed private investigator becomes an invaluable resource.
At Lawrence Ryan Investigations, we’ve worked with stalking victims for over 40 years. What we’ve found is that most victims come to us after they’ve already tried handling it on their own — and after the situation has escalated. The earlier you involve a professional, the more options you have.
Here’s what a licensed PI can realistically do that most people can’t on their own:
Conduct legal surveillance.
A licensed investigator can observe and document a stalker’s movements, patterns, and behavior in public spaces legally. Every piece of footage and every report is gathered in compliance with Illinois law, making it usable as evidence.
Identify an unknown stalker.
If you don’t know who is following you or monitoring you, a PI can run background checks, trace digital footprints, and use skip trace and person location techniques to identify the individual.
Detect spyware and hidden tracking devices.
If you suspect your phone, car, or home has been compromised, our digital forensics team can sweep for stalkerware, hidden cameras, GPS trackers, and monitoring software and remove them safely. An investigator can use digital forensic tools to detect any spyware in mobile phones or other devices.
Build a court-admissible evidence file.
Everything we document is prepared with legal proceedings in mind. Whether you’re filing for a Stalking No Contact Order, pursuing criminal charges, or building a civil case, we give you the organized, timestamped evidence package that attorneys and judges need.
Provide ongoing threat assessment.
Not all stalking situations carry the same level of danger. Our investigators assess behavioral patterns and escalation risk, so you’re not making decisions in the dark.
A private investigator doesn’t replace law enforcement, but we can do what police departments often don’t have the bandwidth to do: sustained, focused, documented surveillance of a specific threat to a specific person.
If you’re not sure whether your situation warrants a PI, that’s exactly what a free consultation is for. Let us help you figure out your next step.
