Below, six of the most common signs of cheating:

  1. Changes in intimacy: A distinct increase or decrease in intimacy, affection levels, and/or sexual preferences may indicate infidelity.
  2. Suspicious phone habits: A spouse that hides his or her phone or is secretive about their call logs and text messages may be cheating.
  3. Changes in appearance: A marked change in style of dress, intimate wear, and/or personal hygiene can be a clue.
  4. Suspicious internet use: Much like phone habits, a cheating spouse may be overly secretive when it comes to their browser history and  general internet and computer habits.
  5. Changes in work routine: It may seem like a cliche but a husband or wife that suddenly needs to “work late” or “go to a conference” frequently is a sign of infidelity.
  6. Changes in bathing habits: A spouse that showers right when they get home, switches cologne or perfume, or changes their grooming habits can be a sign of cheating.

Missing Person: All missing person cases are time sensitive and require immediate attention, you must be ready to act quickly. We have the knowledge and expertise to start the case and get things moving immediately by putting the right plan in place.

Criminal Investigation: A criminal investigation is an undertaking that seeks, collects, and gathers evidence of a crime for a case or specific purpose. A criminal investigator looks for clues and evidence to determine whether a crime has taken place. If a crime has been committed, investigators may look into the background of the accused and try to uncover who committed the crime. Police agencies and law enforcement are committed to criminal investigations of every kind, but a growing number of individuals are choosing to launch their own criminal investigations with the help of professional investigators.

Insurance Fraud Investigation: An insurance fraud investigation is a type of investigation that centers around attempts to benefit from deceitful claims. Seeking compensation for false or inflated claims is illegal, dangerous, and raises the price of insurance for everyone. According to the Coalition Against Insurance Fraud, an estimated $80 billion is paid out annually in fraudulent insurance claims. This leads to the average household paying around $950 each year in higher premiums. In addition, being held liable in a staged accident can increase your risk of being sued. The prevalence of this type of fraud has resulted in insurance companies acting with caution when paying claims, meaning you may need professional help when making your claim. An insurance fraud investigation aids by revealing false claims. Don't let your insurance premiums be a waste of money; use a private investigator to safeguard your insurance privileges. 

Providers of in-depth research investigation services. In today's modern age, it is common to obtain some information using publicly available online databases.
