GPS Tracking: Technology is changing the way private investigators work. Thanks to smartphones and robust databases, investigators no longer need to lug around heavy equipment or rifle through directories. However, new technologies present new legal challenges - and nothing signifies that more than the spread of GPS tracking devices. This level of convenience and power of GPS trackers has proven tempting for all sorts of purposes. Insurance companies and car dealers have used them to track down and repossess cars, spouses have used them to track their significant others, police have used them to trail suspects, and parents have used them to keep their kids safe. Before you go out and plant a GPS tracking device on someone's vehicle you should understand when it’s OK, when the law is unclear, and when it’s most definitely illegal.

Case by Case: When is it OK to use a GPS Tracking Device? Cases involving them have gone all the way to the supreme court. Between the 4th amendment's restrictions on unreasonable search and seizure, various court rulings, and state laws, one thing is clear: putting a GPS tracking device on a car will place you in shaky legal territory. Before we get into how courts have ruled on using GPS trackers in the past, beware -the law is unsettled and subject to change. Oh, and none of this is legal advice or a substitute for legal advice - seek counsel before doing anything.

CIVIL AND CRIMINAL INVESTIGATIONS: C4SEM provides numerous services to attorneys, including surveillance, asset searches, background checks, and polygraphs. We provide the services you need discreetly and confidentially, and our report will bring you one step closer to winning your case.

Skip Tracing/People finding: Skip tracing service can be described as a method of process of locating a fugitive that can't be found at their place of residence or usual hangouts. “Skip” refers to the person being searched for (derived from the term “to skip town”) and “tracing” means the act of locating the skip.  C4SEM  Skip Tracing Service includes but is not limited to:

  • Records Research: Searching for important documents, our investigators will use databases, courthouses, libraries, public service locations that house records, and even the United States Post Office. The kinds of records they look for could include marital, court, business, and financial. The validity of these records is also something they verify.

  • Surveillance: Workplace, relatives, and friends surveillance is often used based on the knowledge and information about the individual, including their habits, schedules, and the locations in which they live, work, and socialize.

  • Background Investigation: Dependent upon the case, our investigators may conduct a background investigation to understand the individual better. This can include interviews with family members, friends, and former colleagues, and looking into criminal records.
